/* Visually hides the camera/upload file inputs without display:none.
 * iOS Safari only honors capture="environment" (jumping straight to the
 * camera app) when the input is still actually rendered at click time —
 * a display:none input (which `hidden` sets) makes it silently fall back
 * to the same generic photo/file picker as the plain upload input, so the
 * "Take photo" button stops doing anything different from "Upload
 * photo(s)". Clipping it to 1x1px off in a corner keeps it out of sight
 * and out of layout while still counting as rendered. */
