  /**
   * Map — a thin, theme-aware wrapper around @studiometa/vue-mapbox-gl's
   * MapboxMap. Pass an `access-token`; drop `<MapMarker>` / `<MapPopup>` /
   * `<MapLayer>` (re-exported from this package) or any @studiometa child into
   * the default slot to build any kind of map.
   *
   * Supports all official Mapbox variants via `variant`:
   * - `streets`: Mapbox Streets v12 navigation & POI basemap
   * - `outdoors`: Mapbox Outdoors v12 topographic & hiking contours
   * - `light`: Mapbox Light v11 monochromatic
   * - `dark`: Mapbox Dark v11 monochromatic
   * - `satellite`: Mapbox Satellite v9 high-res aerial photography
   * - `satellite-streets`: Mapbox Satellite Streets v12 hybrid satellite + street labels
   * - `navigation-day`: Turn-by-turn navigation day palette
   * - `navigation-night`: Turn-by-turn navigation dark HUD palette
   * - `standard`: Mapbox Standard with dynamic 3D lighting & landmark models
   * - `muted`: Desaturated theme-aware minimal canvas for data dashboards
   * - `default`: Theme-aware light/dark basemap
   *
   * Additional 3D features:
   * - `pitch`: Camera tilt angle (0 - 85 degrees)
   * - `bearing`: Camera rotation angle (0 - 360 degrees)
   * - `buildings3d`: Adds 3D extruded building footprint layer
   * - `terrain3d`: Enables 3D digital elevation model (DEM) terrain
   *
   * Requires a Mapbox access token (https://account.mapbox.com).
