/* The public "How to Play" site — on the Frenika Devon brand system.
 *
 * The look is brand.css: the SAME stylesheet every Frenika Devon site ships
 * (canonical copy frenikadevon/assets/css/brand.css, copied here by that repo's
 * `php tools/sync-brand.php` — never edit play/brand.css by hand). Warm paper,
 * plum ink, berry buttons, Fraunces / Mulish / Caveat, the rainbow arch in the
 * header and the plum footer. This file only lays out what is particular to
 * these pages, and uses brand tokens (var(--berry), var(--card) …) for every
 * colour so a brand change reaches here through the sync alone.
 *
 * Load order is style.php (the Puzzle Creator's own assets/style.css) → brand.css
 * → this file. The generator's stylesheet draws the puzzle markup inside a saved
 * example, and it shares a few names with brand.css (:root --ink/--muted/--line,
 * body, .topbar, .btn, .panel, .section-head). brand.css loading after it keeps
 * the page chrome on-brand; the "puzzle sheet" block below then hands the sheet
 * back the generator values its puzzles were drawn with. Nothing here restyles
 * `.puzzle` or any other generator class beyond that — the point of snapshotting
 * the preview HTML is that it looks the same here as in the generator.
 *
 * Tuned for a nervous first-timer arriving from a Patreon link on a phone:
 * generous type, one column, and the answer key behind a deliberate tap.

 * style.php sets these for the generator's own admin screen; brand.css
