   Shared by every page under /docs/.

   Theme model: three states.
     - no data-theme attribute  -> follow the operating system (auto, default)
     - data-theme="light"       -> forced light
     - data-theme="dark"        -> forced dark
   Light is the base palette on bare :root. Dark is redefined twice: once
   under prefers-color-scheme (guarded so a forced light wins) and once under
   an explicit data-theme="dark" (so the toggle wins in both directions).
