/* Layers control — rendered as a native IControl inside the map's control
   stack. Chrome (radius, shadow, white background) comes from the engine's
   ctrl-group classes on the same element; this file styles the contents.

   Per-control custom colors from add_layers_control() arrive as CSS
   variables set inline on the root:
     --lc-bg          background_color
     --lc-text        inactive_text_color
     --lc-active-bg   active_color
     --lc-active-text active_text_color
     --lc-hover-bg    hover_color */
