/* Made to Fit
   Design tokens (Drafting table, October 2026). Drafting paper with a faint grid, navy ink,
   blueprint blue for actions only, orange for measurements only. Drawings are pencil
   sketches: graphite lines, a pale blueprint wash and hand lettering (--hand) for notes on
   drawings only (Kalam). Type: Clash Grotesk headings, General Sans text, JetBrains Mono
   for measurements, all from Fontshare. Shape rule: surfaces use --r (4px); buttons, chips and controls --pill (3px).
   The logo (m mark and Outfit wordmark) is fixed; only its colour follows the tokens. */
