The state colours the view-models hand to bindings — top bar, REC/ON-AIR dots, health banner, meter bands, toast tints — were hex literals in C#. They now resolve from Themes/Tokens.xaml through `Helpers/ThemeBrush`, so the values live in one place. Without an Application (unit tests) the helper returns a neutral grey: visibly wrong rather than silently plausible. Four tokens the code needed and the document lacked, added to DESIGN.md (so the doc-is-the-contract guard demanded their brushes): info-container #3a3b52, success-container #1d5c38, warning-container #b8860b, test-container #9c6f1c (the test-stream gold bar). Also fixed by this: the top bar still painted the RETIRED brand red #e94560 when live — the standard's #ff5451 now, and `OnAirSignTests` (which pinned the old value) says so. BarOn/BarOff became properties rather than static fields, because a static field would resolve tokens before the Application exists. Verified: DesignTokensTests, GameMeterHonestyTests, NotificationAreaIntegrationTests, OnAirSignTests, SessionTeardownTests — 38 tests green.
