What it does
The dropdown header is no longer just `Active` / `Paused` — it tells you why. `Active — CPU 87% > 75% threshold`. `Paused — Camera in use`. `Active — Zoom is running`. `Paused — On battery (18%)`.
How it works
The engine's status reason is an enum with about 20 cases, each with its own localized description. The dropdown reads it directly.
Where to find it
Menu bar → header line.
When to use it
