/* RABBIDS public site stylesheet -- shared by every generated article and
   each project's hub page (backend/agent/render.py). Deliberately its own
   design system, not the internal dashboard's neumorphic one (see
   docs/research/neumorphic-dataviz.md, which is scoped to the dashboard):
   a plain, readable content-site look, system fonts only (no WOFF2 self-
   hosting yet -- avoids all font-loading CLS/LCP risk for v1), one flat
   accent color instead of soft shadows. Written once, copied into
   dist/assets/site.css on every deploy (backend/agent/deploy.py).
