   Dark Mode Support (follows host theme, not OS)

   Activates when an ancestor carries a dark-theme marker from the host site,
   so the map matches the page rather than the visitor's OS setting. Markers:
     - .dark                  (Tailwind class strategy / generic)
     - [data-theme="dark"]    (generic data attribute)
     - [data-bs-theme="dark"] (Bootstrap 5.3+)
   Or add .dark directly on .ol-map-container for explicit per-map control.

   The :where(...) ancestor selectors keep 0 specificity so host styles win
   easily; .ol-map-container.dark keeps its original specificity for explicit
   opt-in. To follow the OS instead, wrap these rules in your own
   @media (prefers-color-scheme: dark) in site CSS.
