/*
 * Play chrome: the one top bar (HUD) and menu (settings panel) used by every game on play.pandupewe.com.
 * Canonical source. Stack and Chess import it at build time; Blob's build prepends it to blob.css;
 * Monopoli ships a byte-identical copy (test/play-chrome.test.js keeps copies in sync).
 *
 * Copy (language, wording) stays per game. Shape, size, order, casing and colour come from here.
 *
 * Fonts    : each game loads IBM Plex Mono + Space Grotesk itself (fontsource, or local @font-face named Plex / Space).
 * Top bar  : <header class="pp-hud"> brand cell, 1-3 metric cells, then 44px vertical action buttons (MENU last).
 * Menu     : <dialog class="pp-dialog"> head (title + close), then sections in this order:
 *            game options -> preference toggles (sound, haptic, reduced motion, night mode)
 *            -> game actions (destructive last) -> back link to the index -> note.
