   community.css — iDive Community module  (flyingfish.live/community/)
   ───────────────────────────────────────────────────────────────────────────
   FULLY ISOLATED. Read community-src/ISOLATION.md before editing.

   Boundary rules baked into this file:
     • Every rule is scoped under `.ffcm-body` and every class is `ffcm-` prefixed
       → nothing here can leak into /shop/, /courses/, the header, or styles.css.
     • This file defines its OWN complete `--ffcm-*` token set with LITERAL brand
       values (copied from the site's design system, not referenced).  It never
       reads a global token, so a future rebrand of styles.css cannot silently
       shift the community UI.  Header/footer chrome is the ONLY shared dependency
       and it is consumed read-only via the build's `<!--@include header-->`.
