Signal indicators are now wider pill badges (40×20px rect) with the role
label (REM/RUN/FLT) embedded inside, replacing the 10px dot+label rows.
Equipment Start/Stop buttons are disabled when:
- auto control is active
- REM = 0 (device in local mode, not accepting remote commands)
- FLT = 1 (fault active)
Button state reacts in real time to WS signal updates via a per-equipment
syncBtns closure registered in state.opsUnitSyncFns.
