/* Deliberately NOT styling #ar-container video here. MindAR computes its
   own cover-fit width/height/offset for the <video> element internally
   (to correctly crop+center the camera feed for the container's aspect
   ratio) and applies that via inline style — forcing width/height:100%
   here fights that calculation and was causing the video to render
   shifted/cropped on real devices. The canvas is sized explicitly in JS
   instead (see main.js), matching the known-working Jabot3D/webAR.html
   reference, which also leaves the video element untouched. */
