/* ══ Community messenger (features/messenger.mjs, ?view=messages) ═══════════
   A night-sky messenger in the Nebula language: a two-pane app on Deck 1 (chat
   list | conversation | optional info drawer) that fills the space beside
   the side navigation; on phones one pane at a time (list → chat, the chat
   takes the whole screen). Own bubbles carry the brand gradient, others sit
   on a raised deck; reactions, receipts and typing dots are small and alive.
   Tokens: community.css. Logical properties throughout (RTL: /sa/); every
   animation stops under prefers-reduced-motion. */
