/* ==========================================================================
   HMI Library — community forum (/forum/ list page + /forum/t/{slug} topic page)
   Loaded after /styles.css: reuses its tokens (--g-*, --p1..--p4, --run,
   --radius*, --shadow*, --font-sans, --font-mono). Self-contained otherwise
   (does not depend on community.css). Industrial calm gray; state colours only
   where they carry meaning (accepted answer = --run, errors = --p1).
   All forum-specific classes are prefixed fm- or scoped to #forum-list /
   #topic-page so they never leak into other pages.
