fix(#1509): expose --nav-active-bg as a themeable token (#1571)

Red commit: 07a69e48eb (CI run: pending — PR triggers first run) Fixes #1509 ## Problem `--nav-active-bg` is defined in `public/style.css` (line 105) and used by every active-state nav link (`.nav-link.active`, `.nav-more-menu .nav-link.active`, plus the responsive blocks), but the customizer has never mapped it into `THEME_CSS_MAP`. Result: presets, per-operator overrides, and server-side `theme.*` config can recolor every other nav token (`navBg`, `navBg2`, `navText`, `navTextMuted`) — but the active-pill background stays stuck on the hardcoded `rgba(74, 158, 255, 0.15)` (light) / dark-mode equivalent. Themes look broken on the one element users stare at. ## Fix Triage-specified path, no scope creep: - Add `navActiveBg: '--nav-active-bg'` to `THEME_CSS_MAP` in `public/customize-v2.js`. - Surface in the Theme tab's advanced color list (`THEME_COLOR_KEYS` derives from the map; adding to `ADVANCED_KEYS` makes it render in the panel). - Add label + hint so the input is self-explanatory. - Seed defaults on the default preset's `theme` + `themeDark` so the rendered value matches today's hardcoded rgba and dark mode doesn't bleed the light value. - Document the new field in `config.example.json` per AGENTS.md config rule. ## TDD Red commit `07a69e48` adds `test-issue-1509-nav-active-bg.js` and wires it into the CI unit-test step. Assertions fail on master (`THEME_CSS_MAP.navActiveBg` is `undefined`; `applyCSS` does not write the variable). Green commit `29d22ff5` makes the assertions pass without touching any other test. ## Verification - `node test-issue-1509-nav-active-bg.js` → 3/3 pass on this branch, 0/3 on master - `node test-customizer-v2.js` → 59/60 (the 1 failure is pre-existing on master, not caused by this PR — same failure with the diff stashed) - pr-preflight: clean (all gates pass) --------- Co-authored-by: corescope-bot <bot@corescope.local> Co-authored-by: Kpa-clawbot <kpa-clawbot@users.noreply.github.com> Co-authored-by: Kpa-clawbot <bot@meshcore-analyzer>

+/**
+ * Regression test for #1509 follow-up: _detectActivePreset() must return
+ * 'default' on a vanilla install (no localStorage overrides, no server-side
+ * navActiveBg).
+ *
+ * The original #1509 patch seeded `navActiveBg` in PRESETS.default.theme and
+ * .themeDark. Because THEME_COLOR_KEYS derives from THEME_CSS_MAP, the new
+ * key joined the per-key equality check in _detectActivePreset(). On a vanilla
+ * install effTheme.navActiveBg is undefined (server config doesn't seed it,
+ * and the user has no overrides), so the comparison
+ *     effTheme.navActiveBg !== 'rgba(74,158,255,0.15)'
+ * was true and 'default' was no longer detected as the active preset.
+ *
+ * Downstream effect: the customize-theme E2E picks the first non-active preset
+ * and clicks it. With 'default' silently un-detected, the E2E clicked the
+ * 'default' button itself, which triggers a localStorage.removeItem instead
+ * of writeOverrides — so the "cs-theme-overrides not written" assertion fired.
+ *
+ * Fix: an undefined value in the effective theme should match ANY preset value
+ * for the same key (the preset's value will become effective via the CSS
+ * cascade anyway). This test asserts that semantic.
+ *
+ * Run: node test-issue-1509-detect-preset.js
