/* ==========================================================================
   Tagufi — Public Web Phase 1
   One stylesheet for every page. No framework, no build step, no external
   requests: the site is uploaded as plain files, so anything it cannot fetch
   from its own web root does not exist.

   THEMES. Light is the token baseline in :root. Dark is applied twice, on
   purpose:
     1. @media (prefers-color-scheme: dark) — for visitors who never touch the
        toggle, including those with JavaScript off;
     2. :root[data-theme="dark"] — set by the toggle, which must win over the
        system preference in BOTH directions. That is why the media query is
        scoped with :not([data-theme="light"]); without it, a visitor on a dark
        OS could not choose light.

   COLOUR. --accent (#FE501D) and the navy are sampled from the app icon, so the
   site and the store listing are the same brand. On light backgrounds the
   accent is only 3.3:1, so links and small text use --accent-ink instead, which
   clears 4.5:1. Both are checked, not assumed.
