     the studio (canvas-toolbar's Front/Back tabs, rulers, zoom-widget,
     pip-preview, icon-toolbar, studio-panel -- not just .canvas-stage, which
     already had touch-action:none). Without this, a pinch gesture with one
     finger landing outside the canvas proper (very easy on a small phone --
     the toolbar row sits right above the card) still lets Android Chrome's
     native page zoom engage alongside the app's own JS-driven canvas zoom,
     which is what was actually causing the out-of-bounds mask to drift
     during pinch-zoom on Android. The viewport meta tag's maximum-scale=1/
     user-scalable=no (see studio.php) doesn't reliably stop this by itself --
     Android Chrome has ignored that attribute for accessibility reasons
     since ~2019 -- touch-action is the mechanism Android actually honors.
     pan-x/pan-y (rather than none) keeps native single-finger scrolling
     working in the side panels; touch-action is computed as the
     intersection down the ancestor chain, so .canvas-stage's own stricter
     touch-action:none (full custom pan+zoom control) still wins there. */
