 * Border-thickness variants — set the `--thickness` custom property which border-painting components
 * read in their `border-width` (or read from rules targeting their children, as Table does for
 * `<th>` / `<td>`). Each component's existing theme hook (e.g. `--card-thickness`, `--table-thickness`)
 * wins over the variant; the variant wins over the component's default.
