/**
 * Profile registry — single source of truth for the BOOK_PROFILE enum.

 * Each profile is a self-contained module that declares its schema + routes

 * the toolkit looks up profile config; bookScaffoldIntegration consumes
 * PROFILES[profile] to drive injectRoute / injectScript calls.
 *
 * To add a new profile: create src/profiles/<name>.ts, then add two lines
 * here (one to PROFILES, one to ChapterFor). The discriminated union of
 * BookProfile = keyof typeof PROFILES updates automatically.
