Defined in: roots/preflight.ts:22

The theme's base stylesheet as a raw CSS string — box-sizing reset, body typography/colour bound to semantic tokens, and the reduced-motion guard. Inject once at the app root. Requires the --tt-* custom properties to be present (via getThemeStylesContent / <ThemeStyles> / <ThemeProvider>).
