Two causes of the fresh-install 'loads, refreshes, loads again' jank:
- The PWA autoUpdate service worker claims the page right after the very
first load, firing controllerchange, which unconditionally reloaded the
page. Now only a *replaced* controller (a real update) triggers reload.
- A single 2s RPC echo decided server-down on first boot, flashing the
BootScreen and then hard-reloading seconds later. A second, 6s attempt
now runs before concluding the backend is down.
