/* Website Brandkit Generator — page styles.

   Built from the Figma frame "Website BrandKit Generator" (node 805:85).
   Chrome uses the site's tokens like the other mini tools; the one local token
   is the card's #1c1c1c, which the design uses and the site has no name for.

   The swatches and the font specimen are CONTENT, not chrome: they show a
   third-party site's colours and typefaces, so they are literal on purpose. */
