Plan step 36. menu.css left Tailwind's unlayered half for material.components, where its `appearance: base-select` on the select ties select.css's `appearance: none` in layer and specificity and loses on order: select.css's block always follows the menu.css it imports. The customizable select would have fallen back to the native list. The select's own opt-in now sits in select.css's @supports block; menu.css keeps the picker's. A test pins where each is written.
