P2: Restoration only happens on normal shutdown paths. A panic, SIGKILL, or SIGHUP (only INT/TERM are handled) leaves Wi-Fi power save disabled. Because the next launch sees it already disabled, it takes no ownership and never restores it, so it stays off until reboot. Consider persisting the changed interface to a state file and restoring it at startup.

Render the loading screen before the Wi-Fi probe.

Guard.begin() performs synchronous netlink requests with a 300 ms timeout. This call runs before drawLoading(), so a slow or non-responsive nl80211 path can leave the previous screen visible and delay cancellation feedback. Call drawLoading() first, then invoke self.wifi.begin(). (raw.githubusercontent.com)

Review comment at @src/app/release.zig at line 495:
In the startup flow, call drawLoading() before self.wifi.begin() so the loading
screen appears before the synchronous Wi-Fi probe; keep both calls in the
existing flow.
