/* shramankumar.com · v1.5 "float": the v1 look with the v2 content, graph and fixes (see site/DESIGN-v2.md for what moved).
   Fonts: Archivo (variable width, smooth at light weights) + JetBrains Mono for telemetry only. Light + dark are both first-class. Every colour lives in the token blocks below;
   nothing else in this file hard-codes a theme colour. Amber FILLS/glows use --signal; amber WORDS use --signal-text.
   Measured contrast (WCAG 2.x; reproduce with `python3 site/contrast.py`; every text pair >= 4.5:1):
   LIGHT  --text 16.7 on --bg, 18.2 on --bg-2 | --muted 7.1 / 7.7 | --faint (#636770, a touch darker than the brief's #686C74,
          which was 4.46 on --bg-3) 5.2 on --bg, 5.7 on --bg-2, 4.8 on --bg-3 | --signal-text 5.7 on --bg, 6.2 on --bg-2, 5.2 on --bg-3
          --ok 6.0 on --bg | --warn 5.9 on --bg | --signal-ink on --signal 10.6
   DARK   --text 16.3 on --bg, 15.5 on --bg-2 | --muted 8.3 / 7.9 | --faint 5.3 on --bg, 5.1 on --bg-2, 4.8 on --bg-3
          --signal-text 11.1 on --bg, 10.6 on --bg-2 | --ok 10.9 on --bg | --warn 8.8 on --bg | --signal-ink on --signal 10.6
   In the browser (computed colour of every visible text style vs its composited background, 1440 and 360 px, both themes; 89-91 styles each):
   0 failures, minimum 4.80:1 light, 4.75:1 dark. Large text (>=24px) is held to 3:1 but all of it passes 4.5. */
