App 2.35.0: the app takes on the Overview style's own colours

While the style shows its own palette (Sci-fi, Cartoon, Aviation, Nixie;
Retro and Terminal with "Original"), the navigation, buttons and titles
take it instead of the accent colour, e.g. turquoise for Retro
(StylePalette, style_palettes.xml). Blueprint and Mascot are removed; a
stored one opens Tiles. The navigation no longer saves view state, which
crashed a restore across the wide and narrow layouts.

+- 2026-10-25 — App 2.35.0: **the app takes on the style's own colours.** While the Overview style
+  shows its own palette — Sci-fi, Cartoon, Aviation and Nixie always, Retro and Terminal with
+  "Original" — the navigation, buttons, switches and titles take that palette instead of the
+  accent colour: Retro turquoise (`retro_lit`), Terminal green phosphor, Sci-fi orange, Cartoon
+  orange, Aviation cyan, Nixie neon orange (`StylePalette`, overlays in
+  `res/values/style_palettes.xml`, laid over the accent overlay in `onCreate`; a style or colour
+  choice that changes the overlay recreates the activity, as an accent change did). The accent
+  colour stays stored for the styles that use it. **Blueprint and Mascot removed** (owner's
+  choice): `BlueprintView`, `MascotView`, `MascotMood`, `MascotCharacter`, `ChibiBase`,
+  `ChibiFigure`, `FoxFigure`, their strings and the Mascot field on Settings; a stored
+  "BLUEPRINT" or "MASCOT" opens Tiles. Fix: the navigation (`nav_bar`) no longer saves view state —
+  it is a ScrollView in the wide layout and a LinearLayout in the narrow one, and restoring one
+  into the other crashed when the width changed (seen on the emulator only; the car's width does
+  not change). Tests (`OverviewStyleTest`: palettes per style, removed styles) and lint;
+  emulator: each palette, the switch to Retro recolouring at once, the width change. Not tried
+  on the car.
