/* owncord — "signal console" redesign.
   Layout: compact gate card; room as a header bar + a responsive grid of member
   tiles + a docked control bar; chat slides in as a side column (.wrap.chat-open).
   Look: deep slate panels, a single "signal green" voice accent, amber secondary,
   mono for data/labels. Single dark theme by design; no external fonts (works offline). */
