   Cashew Web - base stylesheet (/css/site.css). Loaded by every page.
   css/app.css (the /app page) adds app-only rules on top of this file and
   reuses these tokens and classes. Light theme only. No remote resources:
   the fonts below are self-hosted (latin subset, SIL OFL - see /fonts/OFL.txt).
