* (`*, ::before, ::after`, `html`, `body`) only applies inside widget
* descendants and never bleeds onto the host page.
*
* Imports are intentionally granular (`tailwindcss/theme.css` and
* `tailwindcss/utilities.css`) so preflight is NOT pulled in directly.
* Preflight comes only from the scoped-preflight plugin, ensuring every
* preflight rule that ships in the bundle has a `[data-dg-agent]` ancestor
* selector. The full `@import "tailwindcss"` shortcut would inject the raw
* upstream preflight at root scope alongside the plugin's scoped copy,
* leaking the universal selector reset onto the host page.
*
* Together, the bundle ships zero unscoped global selectors AND zero
* unprefixed utility class names. Any consumer of this package writing
* components must use the `dg:` prefix on Tailwind classes.
