+Pure data + string helpers (no PyQt import at module load) so the palette can
+be imported anywhere cheaply, including headless tests. `apply(app)` opts into
+a matching Fusion QPalette for native widgets (dialogs, message boxes).
+
+Brand accent stays the Hyperwall blue (#3b8edb) used by the web remote, so all
+surfaces read as one product. Video cells themselves stay pure black — this
+theme styles the *chrome* (wizard, control bars, overlays), never the frame.
