 * nothing has measured; `height: auto` is not interpolable and a hard-coded
 * max-height either clips a long form or animates thin air. The inner element
 * needs `min-height: 0` or the grid refuses to shrink it below its content.
 *
 * ⚠ NOT `display: none` AND NOT THE `hidden` ATTRIBUTE. The fields inside are
 * real, required inputs: a browser that is asked to report an invalid field it
 * cannot display refuses the submit and says nothing, so a reader would be left
 * pressing a button that does nothing. Collapsed-but-rendered keeps them
 * focusable, which is also what makes :focus-within a real fallback.
