  /* ── theme tokens ─────────────────────────────────────
     Every colour in the templates is a var() off this palette. :root is the
     dark theme (the original look). Light values arrive two ways: when the
     visitor has chosen light (html[data-theme="light"]), and when they have
     chosen nothing and their system asks for light (the @media rule). The
     masthead and footer keep the dark palette in light mode via .on-dark,
     which re-scopes the same tokens - so the white logo and nav stay readable
     and every descendant that uses a token flips with its surface, with no
     per-element overrides. */
