 - `number` (required): Sequential comic number
-- `filename` (required): Image filename in `static/images/comics/`
+- `filename` (required): Image filename in `static/images/comics/` OR list of filenames for multi-image comics (webtoon style)
 - `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`.

+- Set `filename` to a list of image filenames: `['page1.png', 'page2.png', 'page3.png']`
+- Set `alt_text` to either:
+  - A single string (applies to all images): `'A three-part vertical story'`
+  - A list matching each image: `['Description 1', 'Description 2', 'Description 3']`
+- 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)

 Global configuration in `comics_data.py`:
