   ..."` blobs. Hoisting them here means:
     1. Theming knobs ($bg-white / $border-firm) actually affect the staff
        surface — Phase L (dark mode) can swap the tokens in one place.
     2. Renderers can opt in via `Class="notation-surface"` instead of
        copy-pasting six rules into every razor file.
     3. The notation-surface-style-scanner test
        (tests/.../NotationSurfaceStyleScannerTests.cs) keeps the contract
        honest — any future renderer that re-introduces inline colors or
        a flat 480px min-width fails the test.
