 ## Project Overview
 
-Sunday Comics is a Flask-based webcomic website with server-side rendering and client-side navigation. Comics are stored as simple Python dictionaries in `comics_data.py`, making the system easy to manage without a database.
+Sunday Comics is a Flask-based webcomic website with server-side rendering and client-side navigation. Comics are stored as individual YAML files in `data/comics/`, making them easy to manage without a database. Each comic gets its own file for clean organization and version control.
+
+## Fork-and-Customize Architecture
+
+**IMPORTANT:** Sunday Comics is designed for users to fork and customize for their own webcomics. When making changes, maintain the separation between framework code and user customization to avoid breaking upstream updates.
+
+### File Categories
+
+**Core Framework Files** (Updated by upstream - DO NOT modify unless fixing bugs):
+- `app.py` - Flask application logic
+- `data_loader.py` - YAML loading and caching
+- `templates/*.html` - Jinja2 templates
+- `static/css/style.css` - Core framework styles (references CSS variables)
+- `static/js/*.js` - Client-side navigation and functionality
+- `scripts/*.py` - Utility scripts
+- `version.py`, `VERSION` - Version management
+- `Dockerfile`, `docker-compose.yml` - Deployment configuration
+
+**User Customization Files** (Safe for users to modify):
+- `comics_data.py` - Global configuration settings
+- `static/css/variables.css` - Design variables (colors, fonts, spacing, layout)
+- `data/comics/*.yaml` - Comic metadata (except TEMPLATE.yaml)
+- `content/*.md` - Markdown content (about page, author notes, terms)
+- `static/images/*` - User's images and graphics
+
+**Template Files** (Reference only):
+- `comics_data.py.example` - Configuration template showing all options
+- `data/comics/TEMPLATE.yaml` - Comic file template
+
+**Generated Files** (Auto-created, gitignored):
+- `static/feed.rss`, `static/sitemap.xml` - Generated by scripts
+- `data/comics/.comics_cache.pkl` - Comic cache
+- `__pycache__/`, `*.pyc` - Python bytecode
+
+### CSS Architecture
+
+**Two-file CSS system** to separate customization from framework:
+
+1. **`static/css/variables.css`** (User customization)
+   - Contains all CSS custom properties
+   - Organized by category: Colors, Typography, Spacing, Borders, Layout, Transitions
+   - Users edit this file to customize their design
+   - Loaded first in templates
+
+2. **`static/css/style.css`** (Core framework)
+   - References variables from variables.css
+   - Contains structural styles and layout logic
+   - Should not be modified by users (to allow upstream updates)
+   - Loaded after variables.css
+
+**When modifying styles:**
+- Add new design tokens to `variables.css` (e.g., `--color-accent: #ff0000;`)
+- Reference those variables in `style.css` (e.g., `color: var(--color-accent);`)
+- Never hardcode values in `style.css` that users might want to customize
+
+### Configuration Pattern
+
+**`comics_data.py.example`** serves as a reference:
+- Shows all available configuration options with defaults
+- Updated when new settings are added to the framework
+- Users can check this file when merging upstream updates
+- Never imported - purely documentation
+
+**When adding new configuration options:**
+1. Add the option to `comics_data.py` with a default value
+2. Add the same option to `comics_data.py.example` with documentation
+3. Update `CHANGELOG.md` with migration instructions
+4. Consider backward compatibility (provide sensible defaults)
+
+### Best Practices for Code Changes
+
+**DO:**
+- ✅ Add new features to core framework files (app.py, templates, scripts)
+- ✅ Create new CSS variables in variables.css for customizable values
+- ✅ Update comics_data.py.example when adding new config options
+- ✅ Document breaking changes in CHANGELOG.md with migration steps
+- ✅ Test that user customizations (comics_data.py, variables.css) still work
+- ✅ Keep file structure consistent with the fork-friendly model
+
+**DON'T:**
+- ❌ Hardcode design values in style.css that users might want to change
+- ❌ Modify user content files (data/comics/*.yaml, content/*.md)
+- ❌ Change the purpose or structure of user customization files
+- ❌ Remove configuration options without deprecation warnings
+- ❌ Make changes that require users to edit core framework files
+
+**When adding new features:**
+1. Ask: "Will users want to customize this?"
+2. If yes: Add a variable/config option
+3. If no: Implement in framework code
+4. Always maintain the separation
+
+### Upstream Update Workflow
+
+Users following [UPSTREAM.md](UPSTREAM.md) will:
+1. Fork the repository
+2. Customize `comics_data.py` and `variables.css`
+3. Add their comics and content
+4. Periodically merge upstream updates: `git merge upstream/main`
+5. Resolve conflicts (usually only in .example files)
+6. Benefit from framework improvements without losing customizations

+## Versioning
+
+The project uses date-based versioning (YYYY.MM.DD format):
+- **`version.py`**: Python module containing `__version__` variable (import with `from version import __version__`)
+- **`VERSION`**: Plain text file at project root for easy access by scripts and CI/CD
+- **`CHANGELOG.md`**: Tracks version history and changes following [Keep a Changelog](https://keepachangelog.com/) format
+- **HTML meta tag**: Version appears in page source as `<meta name="generator" content="Sunday Comics X.Y.Z">`
+
+When releasing a new version:
+1. Run `python scripts/bump_version.py` to update version files
+2. Edit `CHANGELOG.md` to document changes under the new version
+3. Commit changes: `git commit -m "Release version YYYY.MM.DD"`
+4. Tag the release: `git tag -a vYYYY.MM.DD -m "Version YYYY.MM.DD"`
+5. Push with tags: `git push && git push --tags`

 ## Architecture
 
-### Data Layer: comics_data.py
+### Data Layer: YAML Files in data/comics/
-Comics are stored as a Python list called `COMICS`. Each comic is a dictionary with:
+
+Comics are stored as individual YAML files in the `data/comics/` directory. The `data_loader.py` module automatically loads all `.yaml` files (except `TEMPLATE.yaml` and `README.yaml`), sorts them by comic number, and builds the `COMICS` list.
+
+**Caching:** The data loader uses automatic caching to speed up subsequent loads:
+- First load: Parses all YAML files, saves to `data/comics/.comics_cache.pkl`
+- Subsequent loads: Reads from cache (~100x faster)
+- Auto-invalidation: Cache rebuilds automatically when any YAML file is modified
+- Cache can be disabled via environment variable: `DISABLE_COMIC_CACHE=true`
+
+Performance with caching (1000 comics):
+- Initial load: ~2-3 seconds (builds cache)
+- Subsequent loads: ~0.01 seconds (uses cache)
+- Scripts (RSS, sitemap): All share the same cache file on disk
+
+**File structure:**
+- `data/comics/001.yaml` - Comic #1
+- `data/comics/002.yaml` - Comic #2
+- `data/comics/003.yaml` - Comic #3
+- `data/comics/TEMPLATE.yaml` - Template for new comics (ignored by loader)
+- `data/comics/README.md` - Documentation for comic files
+
+**Adding a new comic:**
+1. Use `python scripts/add_comic.py` to auto-generate the next comic file
+2. OR manually copy `TEMPLATE.yaml` and rename it
+3. Edit the YAML file to set comic properties
+
+Each comic YAML file contains:
 - `number` (required): Sequential comic number
-- `filename` (required): Image filename in `static/images/comics/`
+- `filename` (required unless using html_embed): Image filename in `static/images/comics/` OR list of filenames for multi-image comics (webtoon style)
+- `html_embed` (optional): Custom HTML to embed instead of an image (e.g., video player, widget). Takes precedence over `filename`.
 - `date` (required): Publication date in YYYY-MM-DD format
-- `alt_text` (required): Accessibility text
+- `alt_text` (required): Accessibility text OR list of alt texts (one per image for multi-image comics)
 - `title` (optional): Comic title (defaults to "#X" if absent)
 - `author_note` (optional): Plain text note
 - `author_note_md` (optional): Markdown file for author note (just filename like "2025-01-01.md" looks in `content/author_notes/`, or path like "special/note.md" relative to `content/`). Takes precedence over `author_note`.

 - `plain` (optional): Override global PLAIN_DEFAULT setting (hides header/border)
 - `section` (optional): Section/chapter title (e.g., "Chapter 1: Origins"). Add to first comic of a new section.
 
+**HTML embeds in YAML:**
+```yaml
+html_embed: '<iframe src="https://www.youtube.com/embed/dQw4w9WgXcQ" width="560" height="315" frameborder="0" allowfullscreen></iframe>'
+alt_text: "Video description for accessibility"
+```
+- Use `html_embed` to display custom HTML content instead of an image
+- Useful for embedding videos, interactive widgets, or special content
+- When `html_embed` is present, it takes precedence over `filename` and `mobile_filename`
+- The HTML is rendered as-is using the `| safe` filter in templates
+- No click-through navigation on HTML embeds (use navigation buttons instead)
+- Still provide `alt_text` for accessibility context
+
+**Multi-image comics (webtoon style) in YAML:**
+```yaml
+filename:
+  - page1.png
+  - page2.png
+  - page3.png
+alt_text:
+  - "Description 1"
+  - "Description 2"
+  - "Description 3"

+- Set `filename` to a list of image filenames
+- Set `alt_text` to either a single string (applies to all images) or a list matching each image
+- If `alt_text` is a list but doesn't match `filename` length, a warning is logged
+- Images display vertically with seamless stacking (no gaps)
+- First image loads immediately; subsequent images lazy-load as user scrolls
+- No click-through navigation on multi-image comics (use navigation buttons instead)

+## Keeping Your Fork Up-to-Date
+
+**If you forked Sunday Comics to create your own webcomic site**, you can stay up-to-date with framework improvements while keeping your customizations.
+
+Sunday Comics is designed with a **fork-and-customize workflow**:
+- ✅ **Core framework files** (app.py, templates, scripts) - updated by upstream
+- ✅ **User customization** (comics_data.py, variables.css) - your settings
+- ✅ **User content** (comics, images, markdown) - your creative work
+
+When you pull upstream updates, you'll get new features and bug fixes without losing your content or design.
+
+**📖 [Read the complete guide: UPSTREAM.md](UPSTREAM.md)**
+
+The UPSTREAM.md guide covers:
+- Setting up your fork with an upstream remote
+- Pulling and merging updates
+- Handling merge conflicts (with examples)
+- Understanding which files to modify vs. leave alone
+- Troubleshooting common issues
+
+**Quick update workflow:**
+```bash
+# Every few weeks/months:
+git fetch upstream                    # Get new commits
+git merge upstream/main               # Merge updates
+# Resolve any conflicts if needed
+git push origin main                  # Push to your fork
+python scripts/publish_comic.py       # Rebuild site

+Comics are stored as individual YAML files in the `data/comics/` directory. Each comic file contains:
 
-```python
+```yaml

+  - Panel 3 description
+date: '2025-01-08'
+full_width: true  # Recommended for webtoons

 ### Adding a New Comic
 
 **Option 1: Use the script (recommended)**
 ```bash
-# Add comic entry only
+# Add comic YAML file with defaults
 python scripts/add_comic.py
 
-# Add comic entry AND create markdown file for author notes
+# Add comic YAML file AND create markdown file for author notes
 python scripts/add_comic.py -m
 ```
-This will automatically add a new entry with defaults. The `-m` flag creates a markdown file in `content/author_notes/{date}.md` with a template and adds the `author_note_md` field to the comic entry. Then edit `comics_data.py` to customize.
+This will create a new YAML file in `data/comics/` with the next comic number and reasonable defaults. The `-m` flag also creates a markdown file in `content/author_notes/{date}.md` with a template. Then:
+1. Edit the generated YAML file to customize title, alt_text, author_note, etc.
+2. Upload your comic image to `static/images/comics/`
+3. Optionally create a thumbnail in `static/images/thumbs/` with the same filename
 
 **Option 2: Manual**
-1. Save your comic image in `static/images/comics/` (e.g., `comic-001.png`)
+1. Copy `data/comics/TEMPLATE.yaml` and rename it (e.g., `003.yaml`)
-2. Optionally, create a thumbnail in `static/images/thumbs/` with the same filename
+2. Edit the YAML file to set comic properties
-3. Add the comic entry to the `COMICS` list in `comics_data.py`
+3. Save your comic image in `static/images/comics/`
+4. Optionally, create a thumbnail in `static/images/thumbs/` with the same filename
 
-### Generating RSS Feed
+### Publishing Comics
 
-After adding comics, regenerate the RSS feed:
+After adding or updating comics, use the publish script to update all generated files:
 ```bash
-python scripts/generate_rss.py
+python scripts/publish_comic.py
 ```
-This creates/updates `static/feed.rss`
+This convenience script rebuilds the cache and regenerates both RSS feed and sitemap in one command.
+
+### Comic Caching System
+
+Sunday Comics uses an automatic caching system to speed up comic loading:
+
+**How it works:**
+- **First load**: Parses all YAML files, saves to `data/comics/.comics_cache.pkl`
+- **Subsequent loads**: Reads from cache (~100x faster)
+- **Auto-invalidation**: Cache rebuilds automatically when any YAML file is modified
+
+**Performance (1000 comics):**
+- Initial load: ~2-3 seconds (builds cache)
+- Subsequent loads: ~0.01 seconds (uses cache)
+- Scripts share the same cache file on disk
+
+**Manual cache management:**
+```bash
+# Force rebuild the cache (normally not needed)
+python scripts/rebuild_cache.py
+
+# Disable caching (for debugging)
+export DISABLE_COMIC_CACHE=true
+python app.py
+```
+
+The cache file is automatically excluded from git (listed in `.gitignore`).
 
 ### Markdown Support
 
 **Author Notes:**
-Add the `author_note_md` field to your comic entry in `comics_data.py` to use markdown-formatted author notes. The field can be:
+Add the `author_note_md` field to your comic YAML file to use markdown-formatted author notes. The field can be:
-- Just a filename (e.g., `"2025-01-01.md"`) - looked up in `content/author_notes/`
+- Just a filename (e.g., `2025-01-01.md`) - looked up in `content/author_notes/`
-- A path relative to `content/` (e.g., `"special/intro.md"`)
+- A path relative to `content/` (e.g., `special/intro.md`)
 
 Markdown author notes take precedence over the plain text `author_note` field and render as HTML.
 
 Example:
-```python
+```yaml
-# In comics_data.py
+# In data/comics/001.yaml
-{
+number: 1
-    'number': 1,
+filename: comic-001.png

 **Note:** Client-side navigation displays author notes as plain text. Markdown author notes only render properly on initial page load (server-side rendering). For full markdown rendering, users need to refresh the page or navigate directly to the comic URL.
 
+### Multi-Image Comics (Webtoon Style)
+
+Sunday Comics supports vertical scrolling comics with multiple images stacked seamlessly, perfect for webtoon-style storytelling.
+
+**How it works:**
+- Set `filename` to a list of image filenames instead of a single string
+- Images display vertically with no gaps between them
+- First image loads immediately, subsequent images lazy-load as readers scroll
+- No click-through navigation on multi-image comics (use navigation buttons instead)
+
+**Basic Example:**
+```yaml
+# In data/comics/004.yaml
+number: 4
+title: Webtoon Episode 1
+filename:
+  - page1.jpg
+  - page2.jpg
+  - page3.jpg
+alt_text: A three-part vertical story  # Single alt text for all images
+date: '2025-01-22'
+```
+
+**Individual Alt Text (Recommended for Accessibility):**
+```yaml
+# In data/comics/005.yaml
+number: 5
+title: Long Scroll Episode
+filename:
+  - scene1.png
+  - scene2.png
+  - scene3.png
+  - scene4.png
+alt_text:
+  - Opening scene showing the city at dawn
+  - Character walking through the marketplace
+  - Close-up of the mysterious artifact
+  - Dramatic reveal of the antagonist
+date: '2025-01-29'
+```
+
+**Important:** If you provide `alt_text` as a list, it should match the number of images in `filename`. If the counts don't match, you'll see a warning in the logs. To use the same alt text for all images, just provide a single string instead of a list.
+
+**Features:**
+- ✅ **Seamless vertical layout** - Images stack with no visible gaps
+- ✅ **Lazy loading** - Only loads images as they scroll into view (performance optimization)
+- ✅ **Responsive** - Works on desktop and mobile devices
+- ✅ **Accessible** - Supports individual alt text for each image panel
+- ✅ **Backward compatible** - Single-image comics continue to work as before
+
+**Best Practices:**
+1. **Image consistency** - Use the same width for all images in a multi-image comic for best results
+2. **Alt text per panel** - Provide individual alt text for each image to describe what's happening in that section
+3. **File naming** - Use descriptive, sequential names like `comic-004-panel-1.png`, `comic-004-panel-2.png`
+4. **Image optimization** - Compress images appropriately since readers will load multiple images per comic
+
+**Example with all options:**
+```yaml
+# In data/comics/006.yaml
+number: 6
+title: 'Chapter 2: The Journey Begins'
+filename:
+  - ch2-001.png
+  - ch2-002.png
+  - ch2-003.png
+  - ch2-004.png
+  - ch2-005.png
+alt_text:
+  - 'Panel 1: Hero packs their bag at sunrise'
+  - 'Panel 2: Saying goodbye to the village elder'
+  - 'Panel 3: Walking along the forest path'
+  - 'Panel 4: Encountering a mysterious stranger'
+  - 'Panel 5: Accepting a map to the ancient ruins'
+date: '2025-02-05'
+author_note: This was so much fun to draw! The journey arc begins.
+full_width: true  # Recommended for webtoon-style comics
+section: Chapter 2  # Optional: mark the start of a new chapter
+```
+
+**Technical Details:**
+- Images appear in the order listed in the `filename` array
+- If `alt_text` is a single string, it applies to all images
+- If `alt_text` is a list, it must match the length of `filename` (or it will pad with empty strings)
+- The first image in the array is used as the thumbnail in the archive page
+- Lazy loading uses Intersection Observer API with 50px margin for smooth loading
+
+**When to use multi-image:**
+- Long-form vertical scrolling stories (webtoons, manhwa style)
+- Comics with natural panel breaks across multiple images
+- Stories that benefit from vertical pacing and reveals
+
+**When to stick with single images:**
+- Traditional comic strip or page layouts
+- Self-contained single-panel comics
+- When you want click-through navigation on the comic image

+### Using a CDN for Static Assets
+
+For better performance, especially with high traffic or global audiences, you can serve static assets (images, CSS, JavaScript) from a Content Delivery Network (CDN).
+
+**How it works:**
+
+Sunday Comics includes built-in CDN support through the `CDN_URL` configuration option. When set, all static assets (comic images, CSS, JavaScript, icons, etc.) are served from your CDN instead of your application server.
+
+**Setup Steps:**
+
+1. **Upload your static files to a CDN:**
+   - Upload the entire `static/` directory to your CDN provider
+   - Popular CDN options: Cloudflare, AWS CloudFront, BunnyCDN, KeyCDN
+   - Maintain the same directory structure (e.g., `static/css/style.css` → `your-cdn.com/static/css/style.css`)
+
+2. **Configure Sunday Comics:**
+   ```python
+   # In comics_data.py
+   CDN_URL = 'https://cdn.example.com'  # No trailing slash!
+   ```
+
+3. **Deploy and test:**
+   - Restart your application
+   - Verify images and CSS load from the CDN by checking network requests in browser DevTools
+
+**Benefits:**
+- ⚡ **Faster loading** - Static assets served from edge servers closer to your readers
+- 📉 **Reduced server load** - Your application server only handles dynamic content
+- 💰 **Lower bandwidth costs** - CDN bandwidth is often cheaper than server bandwidth
+- 🌍 **Global performance** - Readers worldwide get fast load times
+- 🛡️ **DDoS protection** - Many CDNs include built-in protection
+
+**Example Configuration:**
+
+```python
+# Local development (no CDN)
+CDN_URL = None
+
+# Production with CDN
+CDN_URL = 'https://d1abc123xyz.cloudfront.net'  # AWS CloudFront example
+CDN_URL = 'https://cdn.yourcomic.com'           # Custom domain example
+```
+
+**Important Notes:**
+- When using a CDN, update your static files on the CDN whenever you make changes
+- Consider using cache-busting techniques for CSS/JS updates (version query parameters)
+- Test thoroughly after enabling CDN to ensure all assets load correctly
+- The `cdn_static` template filter automatically handles URL generation
+- When `CDN_URL` is `None`, Sunday Comics falls back to local static file serving
+
+**Free CDN Options:**
+- **Cloudflare** - Free tier includes CDN and DDoS protection
+- **jsDelivr** - Free CDN for GitHub repositories
+- **BunnyCDN** - Low-cost pay-as-you-go pricing
+

+# Updating from Upstream
+
+This guide explains how to keep your forked Sunday Comics site up-to-date with framework improvements while preserving your customizations.
+
+## Fork-and-Customize Workflow
+
+Sunday Comics is designed to be forked and customized for your own webcomic. The project separates:
+
+- **Core framework files** (updated by upstream) - app logic, templates, scripts
+- **User content files** (your comic data) - comics, images, markdown content
+- **User configuration** (your settings) - config and design variables
+
+When you pull updates from upstream, you'll get new features and bug fixes without losing your content or customizations.
+
+---
+
+## Initial Setup
+
+### 1. Fork the Repository
+
+On GitHub, click "Fork" to create your own copy of Sunday Comics.
+
+### 2. Clone Your Fork
+
+```bash
+git clone https://github.com/YOUR-USERNAME/sunday-comics.git
+cd sunday-comics
+```
+
+### 3. Add Upstream Remote
+
+Add the original repository as an "upstream" remote:
+
+```bash
+git remote add upstream https://github.com/ORIGINAL-AUTHOR/sunday-comics.git
+```
+
+Verify your remotes:
+
+```bash
+git remote -v
+# origin    https://github.com/YOUR-USERNAME/sunday-comics.git (fetch)
+# origin    https://github.com/YOUR-USERNAME/sunday-comics.git (push)
+# upstream  https://github.com/ORIGINAL-AUTHOR/sunday-comics.git (fetch)
+# upstream  https://github.com/ORIGINAL-AUTHOR/sunday-comics.git (push)
+```
+
+### 4. Set Up Your Configuration
+
+**Option A: Track your config in git (recommended)**
+
+Your `comics_data.py` and `static/css/variables.css` files are already set up. Customize them and commit:
+
+```bash
+# Edit your configuration
+nano comics_data.py
+nano static/css/variables.css
+
+# Commit your changes
+git add comics_data.py static/css/variables.css
+git commit -m "Configure site settings and design"
+git push origin main
+```
+
+**Option B: Keep config out of git**
+
+If you prefer to keep your config private:
+
+```bash
+# Uncomment the gitignore lines for config files
+nano .gitignore
+# Uncomment:
+# comics_data.py
+# static/css/variables.css
+
+# Copy the example files
+cp comics_data.py comics_data.py.backup
+# Now comics_data.py won't be tracked
+```
+
+---
+
+## Getting Updates from Upstream
+
+### 1. Fetch Upstream Changes
+
+```bash
+git fetch upstream
+```
+
+This downloads new commits from the original repository without modifying your files.
+
+### 2. Review What Changed
+
+See what's new in upstream:
+
+```bash
+# View commit log
+git log HEAD..upstream/main --oneline
+
+# See which files changed
+git diff HEAD..upstream/main --stat
+
+# Review the CHANGELOG
+git show upstream/main:CHANGELOG.md
+```
+
+### 3. Merge Upstream Changes
+
+```bash
+# Merge upstream into your current branch
+git merge upstream/main
+```
+
+**If there are no conflicts:**
+```bash
+# Push the updates to your fork
+git push origin main
+```
+
+**If there are conflicts** (see next section).
+
+---
+
+## Handling Merge Conflicts
+
+Conflicts may occur if both you and upstream modified the same file. Common scenarios:
+
+### Scenario 1: Framework Added New Config Options
+
+**Example:** Upstream added a new setting to `comics_data.py.example`
+
+**What to do:**
+1. The merge conflict will only be in `comics_data.py.example` (not your `comics_data.py`)
+2. Accept upstream's version:
+   ```bash
+   git checkout --theirs comics_data.py.example
+   git add comics_data.py.example
+   ```
+3. Review `comics_data.py.example` for new settings
+4. Manually add any new settings you want to your `comics_data.py`
+
+### Scenario 2: CSS Variables Conflict
+
+**Example:** Both you and upstream added/changed CSS variables
+
+**What to do:**
+1. Open the conflicted file:
+   ```bash
+   nano static/css/variables.css
+   ```
+2. Look for conflict markers:
+   ```
+   <<<<<<< HEAD
+   --your-custom-variable: #ff0000;
+   =======
+   --new-upstream-variable: #00ff00;
+   >>>>>>> upstream/main
+   ```
+3. Keep both variables:
+   ```css
+   --your-custom-variable: #ff0000;
+   --new-upstream-variable: #00ff00;
+   ```
+4. Save and mark as resolved:
+   ```bash
+   git add static/css/variables.css
+   git commit -m "Merge upstream CSS variables"
+   ```
+
+### Scenario 3: Rare - Core File Conflicts
+
+If you modified a core framework file (app.py, templates, etc.), you may have conflicts.
+
+**Best practice:** Avoid modifying core files. If you need custom behavior:
+- Add new routes/functions instead of modifying existing ones
+- Use template blocks for customization
+- Open an issue/PR to suggest the feature for upstream
+
+**If you must resolve:**
+```bash
+# Open the conflicted file
+nano path/to/conflicted_file.py
+
+# Resolve conflicts manually
+# Then:
+git add path/to/conflicted_file.py
+git commit -m "Merge upstream changes with custom modifications"
+```
+
+---
+
+## File Categories Reference
+
+### Core Framework (Upstream Updates)
+
+**DO NOT modify these files** - you'll get conflicts when merging:
+
+- `app.py` - Flask application
+- `data_loader.py` - YAML loading logic
+- `scripts/*.py` - Utility scripts
+- `templates/*.html` - Jinja templates (unless extending)
+- `static/css/style.css` - Core CSS framework
+- `static/js/*.js` - JavaScript functionality
+- `version.py`, `VERSION` - Version info
+- `Dockerfile`, `docker-compose.yml` - Deployment config
+- Documentation files (README, CLAUDE, etc.)
+
+### User Configuration (You Customize)
+
+**Safe to modify** - tracked in git:
+
+- `comics_data.py` - Your site settings
+- `static/css/variables.css` - Your design variables
+- `data/comics/*.yaml` - Your comic metadata
+- `content/*.md` - Your markdown content (about page, author notes)
+- `static/images/*` - Your images and graphics
+
+### Template Files (Reference)
+
+**Use as reference** - copy to create your versions:
+
+- `comics_data.py.example` - Default configuration template
+- `data/comics/TEMPLATE.yaml` - Comic file template
+
+### Generated Files (Ignored by Git)
+
+**Automatically regenerated:**
+
+- `static/feed.rss` - RSS feed
+- `static/sitemap.xml` - Sitemap
+- `data/comics/.comics_cache.pkl` - Comic cache
+- `__pycache__/` - Python bytecode
+
+---
+
+## Migration Notes
+
+When upstream releases breaking changes, check `CHANGELOG.md` for migration instructions.
+
+**Example migration scenario:**
+
+```markdown
+## [2025.03.15] - Breaking Changes
+### Changed
+- Renamed `SHOW_HEADER_IMAGE` to `HEADER_IMAGE` in comics_data.py
+
+**Migration:** Update your `comics_data.py`:
+- Old: `SHOW_HEADER_IMAGE = True`
+- New: `HEADER_IMAGE = 'title.jpg'`
+```
+
+After merging, check the CHANGELOG and update your config accordingly.
+
+---
+
+## Best Practices
+
+### ✅ DO:
+
+- Keep your fork's main branch in sync with upstream
+- Customize via `comics_data.py` and `variables.css`
+- Add your comics to `data/comics/`
+- Read the CHANGELOG before/after merging
+- Test your site after merging updates
+- Commit your changes regularly
+
+### ❌ DON'T:
+
+- Modify core framework files (app.py, templates, etc.)
+- Delete or rename upstream files (you'll break updates)
+- Force push over merged commits
+- Ignore merge conflicts (resolve them properly)
+
+---
+
+## Troubleshooting
+
+### "I modified a core file and now I have conflicts"
+
+**Option 1: Keep your changes** (advanced)
+```bash
+# Resolve conflicts manually, testing thoroughly
+git mergetool
+git commit
+```
+
+**Option 2: Discard your changes** (start fresh)
+```bash
+# Reset to upstream version
+git checkout upstream/main -- path/to/file.py
+git add path/to/file.py
+git commit -m "Reset to upstream version"
+```
+
+### "I want to see what changed before merging"
+
+```bash
+# Create a test branch
+git checkout -b test-upstream-merge
+
+# Merge in the test branch
+git merge upstream/main
+
+# If you like it, merge to main
+git checkout main
+git merge test-upstream-merge
+
+# If not, delete the test branch
+git checkout main
+git branch -D test-upstream-merge
+```
+
+### "My site broke after merging"
+
+```bash
+# Check what changed
+git log --oneline -10
+
+# Test the previous version
+git checkout HEAD~1
+python app.py
+
+# If it works, the issue is in the latest commit
+git checkout main
+git diff HEAD~1 HEAD
+
+# Read CHANGELOG for migration notes
+cat CHANGELOG.md
+```
+
+---
+
+## Getting Help
+
+- **Check the docs:** `README.md`, `CLAUDE.md`, `CHANGELOG.md`
+- **Report issues:** [GitHub Issues](https://github.com/ORIGINAL-AUTHOR/sunday-comics/issues)
+- **Ask questions:** Open a discussion or issue on GitHub
+
+---
+
+## Summary
+
+**Regular update workflow:**
+
+```bash
+# Every few weeks/months:
+git fetch upstream                    # Get new commits
+git log HEAD..upstream/main --oneline # Review changes
+git merge upstream/main               # Merge updates
+# Resolve any conflicts
+git push origin main                  # Push to your fork
+python scripts/publish_comic.py       # Rebuild site
+```
+
+Your comics, images, and config stay safe - only the framework code updates!

+# Comic Data Directory
+
+This directory contains YAML files for managing individual comics. Each comic gets its own `.yaml` file.
+
+## Quick Start
+
+### Adding a New Comic
+
+1. **Copy the template:**
+   ```bash
+   cp TEMPLATE.yaml 004.yaml
+   ```
+
+2. **Edit the file** with your comic's information:
+   - Update `number`, `filename`, `date`, and `alt_text` (required)
+   - Add optional fields like `title`, `author_note`, etc.
+
+3. **Save the file** and restart your application
+
+The comics will be automatically loaded and sorted by comic number.
+
+## File Naming
+
+You can name files anything you want (e.g., `001.yaml`, `first-comic.yaml`, `2025-01-01.yaml`), but using the comic number is recommended for easy organization.
+
+## Required Fields
+
+Every comic MUST have:
+- `number` - Sequential comic number (integer)
+- `filename` - Image filename (string) or list of filenames for multi-image comics
+- `date` - Publication date in YYYY-MM-DD format (string)
+- `alt_text` - Accessibility description (string or list for multi-image)
+
+## Optional Fields
+
+- `title` - Comic title (defaults to "#X" if not provided)
+- `mobile_filename` - Mobile-optimized version
+- `author_note` - Plain text note below the comic
+- `author_note_md` - Markdown file for author note (overrides `author_note`)
+- `full_width` - Override global width setting (boolean)
+- `plain` - Override global plain mode (boolean)
+- `section` - Start a new section/chapter (string, add only to first comic of section)
+
+## Multi-Image Comics (Webtoon Style)
+
+For vertical scrolling comics with multiple images:
+
+```yaml
+number: 42
+filename:
+  - page1.png
+  - page2.png
+  - page3.png
+alt_text:
+  - "First panel description"
+  - "Second panel description"
+  - "Third panel description"
+date: "2025-01-01"
+```
+
+## Example
+
+```yaml
+number: 4
+title: "The Adventure Begins"
+filename: comic-004.jpg
+date: "2025-01-22"
+alt_text: "A hero stands at the edge of a cliff, looking at the horizon"
+author_note: "This is where things get interesting!"
+full_width: true
+section: "Chapter 2: The Journey"
+```
+
+## Validation
+
+The data loader will:
+- Skip files with missing required fields (with warnings)
+- Check for duplicate comic numbers
+- Warn about gaps in numbering
+- Sort comics by number automatically
+
+## Testing Your Changes
+
+Test the loader directly:
+```bash
+python data_loader.py
+```
+
+This will show you all loaded comics and any validation warnings.
