/* Modelwright Studio — dark register
   A dark-ground reading of MODELWRIGHT_STUDIO_STYLE_GUIDE.md: same semantic
   roles (cobalt = structure, pine = human/craft meaning, amber = signal),
   same DotGothic16 display face, same square/thin-border/offset-shadow
   geometry — inverted onto a charcoal ground instead of warm paper. Bright
   variants of cobalt/pine exist so text clears WCAG AA against the dark
   background; the original darker hexes remain for hairline rules and
   borders, where full-contrast tone isn't needed.

   Body copy is set in a real bitmap-font remake — IBM's actual VGA 8x16
   text-mode ROM font, not a coding-monospace approximation — via the
   Ultimate Oldschool PC Font Pack (fonts/ATTRIBUTION.txt has the credit
   this CC BY-SA license requires). A Tandy 1000 remake ships alongside it;
   swap --mw-font-body to "Tandy 1000" to try that face instead. */
