 - CI check `npm run lint:mocks` (wired into `.github/workflows/verify_build.yml`) fails the build if a prototype HTML file under `docs/public/projects/` doesn't reference the shared banner; allowlist supported for deliberate exceptions (currently `deltag-aarhus`)
 - Migrated all eight prototypes (opkraevningsoverblik, salary-negotiation, climate-nudging × 3, agentic-orchestration, book-aarhus, deltag-aarhus-timeline, wcag-contrast-checker) onto the shared component, removing six per-prototype banner copies
 
+### Fixed
+- Mock button (`Åbn prototypen`) hover state — text now stays white against the brand background instead of inheriting the default link color, which made the label nearly invisible
+
 ### Added — Opkrævningsoverblik BBR-beregner
 - New "Beregner" tab in the Opkrævningsoverblik prototype that calculates four BBR-driven municipal fees: rottebekæmpelse (with the >250 m² rate split), renovation, skorstensfejer, and ejendomsskat (grundskyld)
 - Editable mock-BBR data (grundareal, grundværdi, bygninger med type/m²/ildsteder) per test user with per-field reset and live recalculation
