   mybath — remodel scene
   A greyed isometric room where hovering a fixture lights it up.

   Two assets carry the whole thing: the room render, and a pick-map PNG whose
   red channel encodes a part id per pixel (0 = background). Hit-testing is a
   single array lookup, and the highlight is drawn into one canvas — no
   per-part DOM nodes, no N mask files, constant memory regardless of part
   count. Swapping a fixture for a different finish later is the same
   operation with a different source image (see paint() in remodel.js).
