/* ============================================================
   m4th club — THE DARK ANNUAL · shared design system
   A product studio's annual report, rendered on a near-black
   instrument stage. Editorial bones · one warm-brass accent.
   Instrument Serif (display) / Instrument Sans (body) / Geist Mono (utility).
   This single sheet renders every page identically: landing,
   Carillon overview, and the four chapter pages.
