/* ── Stage 20.2 / 20.2.1 / 20.2.2: branded intro (decorative, once per tab) ──
   Shown only while theme-init.js has put .pi-intro-active on <html>. Pure CSS overlay on the
   root element's pseudo-elements: no extra DOM, no layout space, never interactive, never
   focusable. The page underneath renders at full speed and stays perceptible through a
   semi-opaque themed layer (--pi-intro-overlay).

   Choreography (times from the start of the outro; the 600ms brand hold comes first):
     0-300ms     the overlay colour fades to transparent: the site is revealed
                 (logo and ring stay fully opaque)
     300-450ms   the ring fades out (it is retired before the logo)
     450-500ms   only the logo remains, fully visible and the page fully usable
     500-800ms   the logo fades softly: the intro ends
   ::before carries overlay + logo; ::after carries the ring.

   HARD FAILSAFE: the same outro also runs on its own, starting at 1.0s and done by 1.8s, whether
   or not any JavaScript keeps running. The normal path (JS adds .pi-intro-done after the hold)
   uses identically defined keyframes under different names, because a browser only restarts an
   animation when its NAME changes. */
