Plan step 36 review. interaction.css read `data-dragged` beside
`data-md-dragged` while <x-card> still set the old name; the card now
sets the new one and nothing in the package renders the old one on an
element with the class, which 2.0.0 introduces. The Tailwind
`state-layer` utility keeps `data-dragged` until step 39 deletes it.
UPGRADE.md's card line named the old `data-card` hook.

Plan step 33. foundation.css is the one required import: the full
material layer statement, then plain imports of its parts, each opening
with the same statement.
- foundation/reset.css (material.reset): Tailwind 4's preflight rule for
rule, with M3's on-surface-variant placeholder and no typeface.
- foundation/hidden.css: [hidden] and [x-cloak], outside every layer.
- foundation/tokens.css (material.tokens): the token files.
- foundation/base.css (material.base): the page's surface, ink and
brand typeface, and the font face.
- foundation/interaction.css (material.base): md-state-layer,
md-focus-ring, md-touch-target and md-link, the plain-CSS forms of the
utilities; md-state-layer also takes data-md-dragged, and
md-touch-target is 48px (space600) where the utility reads 3rem.
