# ChapterIntro

The structured front matter of an intro chapter (set_chapter_intro): a cover with kicker, title and byline, then up to 20 sections. Strings are trimmed and empty ones dropped; the whole object is at most 150,000 characters of JSON. Photos are storageIds the intro owns: a write that drops one deletes the file (for a live guide, at the next publish).

Group: Chapters.
