/* ── Theme toggle: circular reveal on mode change ──
   Progressive enhancement via the View Transitions API. The incoming theme wipes
   in as a circle growing from the toggle button. Browsers without
   startViewTransition (or anyone with reduced-motion) skip it and fall back to the
   300ms colour cross-fade above — the JS decides. `.theme-anim` freezes those
   colour transitions while the snapshot is captured so the circle reveals the FULL
   new theme, not a half-faded frame. mix-blend-mode:normal overrides the UA
   plus-lighter blend, which would otherwise blow the overlap out to white. */
