Plan step 37: an application on 1.x-style imports now imports
foundation.css before @import 'tailwindcss' and tailwind.css after it,
the way foundation.css's own header has described since Phase F
started — material.css only ever saved writing those two lines.
Updates every place that named it: tailwind.css's and
foundation/hidden.css's and tokens/utilities.css's header comments,
the development skill's install snippet and Tokens section, README.md's
install snippet, and a new line in UPGRADE.md's migration notes.

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.

Plan step 33. Each token file now opens with the material layer
statement and wraps its declarations in material.tokens (the font face
in material.base), so an application's unlayered scheme outranks the
package default whatever the selectors, and the foundation can import
the files with no layer() on the import.
The type-* and state utilities move to tokens/utilities.css, still
imported by material.css, so no file the foundation imports carries a
Tailwind directive. [x-cloak] moves beside the [hidden] rule in
foundation/hidden.css, outside every layer; material.css imports it.
