/* ═══════════════════════════════════════════════════════════════════════
   TriageForge — "Annual Report" theme (v5, 2026-09-14)
   Brings every remaining page into the register of the redesigned
   homepage: white paper, near-black ink, one oxblood spot colour,
   Bodoni Moda headings over IBM Plex Sans body.
   Loaded AFTER each page's own <style> block, so it wins the cascade.
   The pages' own stylesheets are left untouched.
