/* ── User manual (/help) ──────────────────────────────────────────────
 *
 * Loaded after style.css, and only on the manual pages. It reuses the
 * app's theme variables (--surface, --accent, --text-muted …) so the
 * manual follows whichever theme the reader picked in the app, and adds
 * the one thing the app has no use for: long-form reading measures.
 *
 * The app's own rules assume the SPA shell (.screen is display:none
 * until made active, #app is a full-height flex column). The manual has
 * neither, so everything here is scoped under .manual-body.
