   grapestrap.org — site.css
   Site-wide stylesheet layered over vendored Bootstrap 5.3.8.
   Approach: bridge the design tokens from the 2026-08 hand-rolled
   template (grape-green accent, dark default, Inter + JetBrains
   Mono) onto Bootstrap's CSS variables (--bs-*) so stock
   components — buttons, tabs, cards, badges, navbar — pick up the
   look without per-component rewrites. Purpose classes follow.
   Load order: bootstrap.min.css first, then this file.
