/* --------------------------------------------------------------------------
   SECTION 1 — LEGACY (deprecated, moved from styles.css)
   These classes were used by the old messages.js render path.
   The new premium system uses .fcc-msg-* / .fcc-message-* namespaces instead.
   Kept here only to avoid breakage if any external reference remains.
