Before: clicking Dashboard / States / Services / Settings highlighted
the active nav button but the page content never changed. AppShell
dispatched `hc-navigate` events but no listener acted on them.
After (~232 LOC across 4 files):
- main.ts (+20 LOC) tiny router: NAV_TO_TAG maps nav id → page
custom element; on `hc-navigate`, swap the AppShell's child.
- pages/States.ts (~86 LOC) HA-style entity table with 5 s refresh.
- pages/Services.ts (~82 LOC) domain-grouped service registry,
friendly empty state when no services registered.
- pages/Settings.ts (~90 LOC) backend config readout + bearer-token
editor (localStorage["homecore.token"]).
Browser-verified all 4 nav clicks swap content; 0 console errors.
Dashboard → 10 entity cards; States → 10-row table; Services →
empty state (0 domains); Settings → config + token editor.
