/* customise_menu_html — every rule from the form's old <style> block,
   carried across unchanged except for the scoping.

   .cm-root is the adopted form root and stays a BARE rule: it carries the four
   accent custom properties the shared .px-* chrome reads off the form root.
   Nothing is added to it — this form is a screen inside the shell's content
   slot, not a body rule moving onto a root, and no descendant resolves a
   percentage height or flexes against it.

   Four rules are compounded with .px-card. A head <link> loses a padding tie
   to .px-card { padding: 20px } on document order, so they win on
   specificity instead.

   No .themed-scrollbar rule: that class stays the dependency's. */
