 * positions/scales the canvas inside it entirely via a CSS transform, so
 * the canvas's own width/height attributes (its native pixel resolution)
 * are never touched here; the canvas being position:absolute also means it
 * contributes no intrinsic width to this element, which is what makes
 * width:100% safe inside a grid column. touch-action:none keeps native
 * browser touch-scroll/pinch off the canvas so pointer events receive raw
 * touch input for ZoomPanController's own pan/pinch handling.
