User feedback: the Grid toggle button was on every page and showed an
explanatory empty state when classifier wasn't available — adding UI
to explain why UI didn't work. Cleaner approach: drop the button,
make the URL the source of truth, and default grid mode automatically
inside the only context where it's meaningful.
Behavior:
- Inside any incoming/ path (case-insensitive segment match):
→ grid mode by default
- Everywhere else:
→ browse mode
- Explicit overrides via query string:
?view=grid forces grid (only honored where classifier is
available; otherwise falls back to browse)
?view=browse forces browse (always)
UI changes:
- The Browse/Grid pill toggle is gone.
- grid.js drops both empty-state messages; outside an incoming/
path it just does nothing.
- events.js owns resolveViewMode() / applyResolvedViewMode(),
called on initial mount and after every client-side rescope
(dblclick + popstate).
