- Performance: cache the chain index (was rebuilt on every navigation) and
warm it at startup — .bch pages open near-instantly after the first.
- Loading indicator: indeterminate bar under the toolbar, per-tab spinner,
and reload⇄stop button (driven by did-start/stop-loading + BNS resolve).
- Chrome cleanup: removed the bottom status bar and the redundant search
box; security padlock now always present at the front of the address bar;
minimal ICANN/BCNR pill at the end; favorites bar shows only on new-tab.
- Search: added Yandex; engine picker moved into Settings > General.
- Settings redesigned with a left sidebar (General / Performance / Privacy /
Anti-fingerprinting). Anti-fingerprinting now Show/Hide/Spoof/Manual for
timezone, language, AND location (geolocation coords overridden in-page).
