POST/v1/emergencies
Trigger an emergency takeover across a set of screens. An emergency takes the highest priority and layers over each screen's normal content, so clearing it restores exactly what was playing before.
Takes over the chosen screens now, above every schedule and cast, until cleared or expired. Clearing restores exactly what was playing.
**Notes.**
- The route is gated by emergency-override.create; the route registry's description names emergency-override.trigger, which is not a permission the API checks.
