REPL does not load app.css, causing Flowbite-Svelte theme colors to be missing

[shinokada]

Flowbite-Svelte loads correctly in the Svelte REPL, but its components (e.g., Button, Alert, etc.) do not display the correct default theme colors. This happens because the REPL environment does not import the app.css file, which includes the necessary Tailwind CSS configuration and theme variables.

It would be great if the REPL could support importing or referencing app.css, so that Flowbite-Svelte components render with their intended styles out of the box.

// app.css
@import "tailwindcss";
@source "../node_modules/flowbite-svelte/dist";
@theme {
  --z-index-100: 100;

  --color-primary-50: #fff5f2;
  --color-primary-100: #fff1ee;
  --color-primary-200: #ffe4de;
  --color-primary-300: #ffd5cc;
  --color-primary-400: #ffbcad;
  --color-primary-500: #fe795d;
  --color-primary-600: #ef562f;
  --color-primary-700: #eb4f27;
  --color-primary-800: #cc4522;
  --color-primary-900: #a5371b;
}
