   Identity: "pressed fern" — pearl-white paper, deep garden green, a
   Dancing Script signature for the site title. Pearl (light) is the
   default theme; [data-theme="dark"] overrides the tokens with the
   green-tinted ink look. Every color/size decision lives in :root so
   the whole site can be re-skinned from one block. All text tokens hold
   >= 4.5:1 contrast in both themes.
