+## Segmented selectors
+
+Segmented selectors use the controlled DOM adapter in `ui/segmentedControl.js`
+and the shared `gev-segmented` / `gev-segment` surface. Model coverage, label
+allocation, drawing shape, Street View fit/panorama filters and imagery mode keep
+their feature-owned values, actions and persistence. Painting a restored value
+does not emit a change or move focus. Existing keyboard policies remain explicit:
+Street View uses arrows/Home/End with one tab stop, imagery mode uses arrows from
+its controlled selection, and Display keeps its existing native button behavior.
+Pure value navigation is separate from DOM rendering for reuse by a future view.
+Segments keep their word minimum width: compact inline groups such as FIT/FILL
+and ALL/360°/FLAT must not break short labels mid-word. Collapsed Weather follows
+the same exclusive-rail hiding rule as the other readouts.
