feat(web): port design-system tokens + restyle components (#51)

* feat(mobile): BrushOverlay surface + MapLibre preview layer

* refactor(mobile): cache preview color + doc brush overlay

* feat(web): port design-system tokens + restyle components

Introduce a token layer (CSS custom properties + JS export) and load
Manrope / JetBrains Mono fonts. Restyle existing components to use
spec tokens — aqua brand, light-grey bg, panel/sm shadows, radius
scale, typography roles — while keeping current layout, behavior,
and tests intact. Rating ramp swatches and map overlay now pull
from the spec ramp. Map style (bicycle-style.js) untouched so the
mobile style artifact stays in sync.

Also: gear icon in SearchBar grows 25% and centers vertically.

* fix(web): gear icon position + size refinements

* feat(web): self-host Manrope + JetBrains Mono via @fontsource-variable
