/* ---- 5. basin focus indicator ----
   Leaflet ships no focus affordance of its own, so the browser's default
   :focus-visible ring lands on the basin's SVG <path>. Chrome draws `outline`
   on SVG at the element's BOUNDING BOX, which renders as a stray rectangle
   around the selected basin. Suppress the outline entirely and express focus
   through the path's own `stroke`, which follows the real polygon boundary.
   Leaflet sets stroke/stroke-width as presentation attributes and CSS beats
   those, so this needs no change to styleBasin().
   The white drop-shadow halo makes a two-tone indicator that clears WCAG
   1.4.11 (3:1) on all three basemaps — no single flat colour does. The two
   busy ones set the requirement: an orange ring alone loses contrast against
   the Terrain hillshade's mid-tone relief and against the USGS Topo sheet's
   brown contour hatching, and a light ring disappears on the Light basemap. */
