/* Design tokens (palette + semantic + type + shape) live in tokens.css, which
   Propshaft loads before this file. This stylesheet consumes the semantic
   variables only — no raw colors, so the palette can be re-skinned in one place.

   Aesthetic: Vercel Geist. Off-white canvas, gray-1000 ink, hairline gray-400
   borders, soft raised-card shadows, 6px corners, Geist Sans headings at weight
   600 with tracking that tightens as size grows, Geist Mono for codes (opening
   IDs, coordinates, timestamps). Neutral (gray-1000) primary action; blue-700 as
   the link/focus accent. Dark theme is the same tokens via prefers-color-scheme. */
