/* ────────────────────────────────────────────────────────────────
   Hidden-view animation freeze. Inactive views stay in the DOM at
   opacity:0 (they are NOT display:none), so every infinite CSS
   animation inside them — home energy flow-pulses, leaves, halo
   glint, orb breathe, spinners, etc. — keeps burning compositor +
   main-thread work off-screen. Freeze animations on every non-active
   view (generalises finish-kit's home-only rule).

   Scope notes:
   · ONLY animations are paused — transitions are untouched, so the
     .48s view enter/exit opacity/transform transitions keep working.
   · animation-play-state is NOT inherited, so pseudo-elements need
     explicit selectors (both the view's own and every descendant's).
   · #intro and the download gate are .screen, not .view — untouched.
   · The rule drops the instant a view gains .is-active, so its
     entrance choreography (incl. home's replayed .home-motion arc)
     runs normally on becoming active.
   · !important is required: many source animations are themselves
     declared with !important.
   · content-visibility:auto deliberately NOT applied — inactive views
     sit within the on-screen view-stage, so it would yield ~zero skip
     while risking a layout shift on switch. Design is sacred. */
