/* fcc.cc/library — writing published here.
 *
 * Verse reading, the author studio and editor, the published index, writer
 * pages, the mature interstitial and the preview banner. Loaded after
 * styles.css so it can lean on the existing class vocabulary (.lib-btn,
 * .lib-pill, .lib-toast, .shelf-grid, .book-card, .section-head).
 *
 * Rules:
 *   - colour, type, space, radius and motion come from tokens.css only, so
 *     light, dark and (if it is ever promoted) sepia all work with no block
 *     of their own here
 *   - no colour literal appears below at all: every colour is a token, or a
 *     color-mix() of a token with the work's own palette hue
 *   - every keyframe animation has a prefers-reduced-motion opt-out
 *   - 44px minimum tap targets on controls, :focus-visible on everything
 *     focusable
 *
 * Wired in Phase 2 push iii (linked from index.html, added to the service
 * worker CORE_ASSETS with its own ?v= token).

 * a narrower measure than prose, and real stanza gaps. The indent classes
 * vi-1 … vi-12 are emitted by api/app/text_render.py; the editor preview
 * emits the same markup through lib/verse.js.
