/* Hashiwokakero (Bridges) board: islands scattered over a sparse grid
   rather than a filled one, so - like Fanorona/Hex/WallMaze/Go - it's
   rendered as absolutely-positioned circular island buttons over a
   single SVG line layer, with the container's height JS-enforced from
   its measured width each time it's built or the window resizes (CSS
   `aspect-ratio` is unreliable on E-Ink browsers; see hashi-app.js's
   ensureHashiBoardAspect). Every candidate bridge connection is drawn as
   an SVG line UNDER the islands, same as Fanorona's connection lines,
   but unlike Fanorona's purely decorative lines these ARE the primary
   clickable element: an invisible wide "hit" line sits under a thin
   visible one (or two, offset apart, for a double bridge) that's shown
   or hidden as bridges are placed/removed. */
