Subject: [PATCH] Move the select's rules out of the field into select.css
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

<x-select> marks its field root data-md-select, and what a <select>
changes in the field — covering the whole box, the customizable
select's closed button, the focused look and turned arrow while open —
moves from field.css to components/select.css (plan step 36). The open
list stays in menu.css until the menu leaves Tailwind.
