/* =============================================================================
   Horus Heresy — Setup & Reference Utility
   Theme: the Rules of Play rulebook (Fantasy Flight Games, 2010).
   - Cover (p.1): the Warhammer 40,000 / Horus Heresy logo on a blood-red ground, Horus in his armour,
     a riveted steel frame → the masthead.
   - Interior pages (p.2–44): white stock with soft grey horizontal stripes (#ffffff / #f2f1ef), held in a
     rusted machinery frame with a row of skulls (top left) and a yellow glow strip along its inner edge;
     headings in Agency FB Bold, plum #530832, the first level ruled underneath (p.2, p.14); body in
     Bell Gothic Bold, ink #221f1f; sub-heads in plum capitals (p.3, p.8); "»" sub-bullets (p.3);
     page numbers set as ‹ 14 › on a steel plate.
   - Callout boxes (p.6, p.17, p.24, p.27): a rusted girder frame capped by a capsule of skulls.
   - The two sides: the initiative markers (p.8) — Imperial = white aquila on blue in a steel ring,
     Traitor = white Chaos star on red in a bronze ring.
   - The board's initiative track (p.14–15): steel grille cells; Event (red-black, yellow type),
     Order (orange square), Refresh (cyan ring), Spaceport Victory (yellow).
