/* Global dark and light theme (Phase 3).

   One state on the root element, set before first paint by the inline
   script in partials/head.html:  <html data-theme="dark|light">
   Saved in localStorage under "joyjeet-theme"; otherwise the operating
   system preference; otherwise dark.

   Every colour on the site resolves to the semantic tokens below. The
   mirrored Lioré variables, the Dario and Allex section variables and the
   inner-page surfaces (pages.css) are all mapped onto them, so no component
   carries theme specific hex values.

   Surface roles (each keeps the dark / light rhythm in both themes):
     base     .surface, body, footer, page heroes      bg-secondary
     base     .hero, .section, In Numbers, .surface--black, Dario   bg-primary
     inverse  .surface--light                          surface-inverse
     muted    figure fills, card surfaces              surface-secondary / primary */
