/* ── Safari: wash each tile instead of the pane ─────────────────────────
   WebKit gives Leaflet's tiles their own compositing layers, and a composited
   descendant escapes an ancestor's `filter` and `mix-blend-mode` entirely —
   so the wash above never reaches them and the map shows raw OpenStreetMap
   colour. The old answer was `L.Browser.any3d = false`, which put the tiles
   back in normal paint order but also stopped Leaflet ever *scaling* them:
   pinch-zooming then flung the tile container off-screen and left bare
   parchment until you lifted your fingers.

   So each tile is washed on its own instead, and the paper is multiplied in
   by `#on-paper` rather than by a blend mode. Nothing here depends on an
   ancestor or on compositing, which means Leaflet can transform and scale the
   panes as much as it likes — and does, because `any3d` stays on.

   `#ink-flat`, not `#ink-rough`: the wobble displaces by 6px, which per tile
   would drag transparent pixels in at every tile edge and show seams. */
