Extract CSS from TypeScript template literals into standalone .css files
(variables.css, layout.css, components.css, utilities.css) and update
src/routes/admin/ui.tsx to import them directly via Wrangler text imports,
concatenating the strings at runtime for the inline <style> tag.

Add [[rules]] type = "Text" globs = ["**/*.css"] to wrangler-example.toml
so Wrangler bundles .css files as raw text strings importable in TypeScript.
Add src/types/css.d.ts to provide the module declaration for `import css from "*.css"`.
