   MFR FORGE — visual design
   Aesthetic: "flight-line office" — deep Air Force ultramarine chrome, warm
   paper preview, condensed display type (Oswald) over Public Sans, with a
   thin gold service stripe as the accent.

   THEMING (Theme Agent): every surface color routes through the variables
   below. html[data-theme="dark"] overrides them for dark mode. The preview
   sheet (.sheet) intentionally does NOT use theme variables — the document
   preview, like the Word and PDF exports, is always official white-page
   style in both themes.
