/* Anvil docs — one stylesheet. Brand values come from the marketing site's theme
   (packages/anvil-theme in the anvil monorepo): black #10181B, lime #B4E33D, coral #f45d4a,
   Syne for headings. Light palette on :root, dark palette on [data-theme=dark] and on the
   system preference when the theme is "auto". The lime is used as the dark-mode accent and as
   the highlight colour in light mode; link text in light mode uses a darker green that meets
   contrast on white. */
