/*
  Styling for the drop-in install page.

  Deliberately plain and token-based: every colour, radius and font is a custom
  property on :root, so the ForgeSparse site can override them in one block and keep
  its own look without touching the markup. Nothing here is imported from the
  extension — the page has to stand on its own on a web server.

  Dark mode follows the visitor's system setting, and every interactive element keeps
  a visible focus ring.
