/* =============================================================================
   Content report overlay — one stylesheet for all five report surfaces
   (section test, dynamic exam, road signs, 3D driving game, 2D parking game).

   Self-contained on purpose: the two game pages load no Bootstrap and no
   `smartdrive.css`, so every colour is declared inside the overlay's own
   scope rather than inherited from the host page. The host page only decides
   light or dark.

   The design language follows DESIGN.md — the asphalt ink for text, signal
   blue for the primary action, amber kept away (it is reserved for premium
   status and warnings), and hairline rules instead of heavy borders.
