/* Entrance animation — PURELY ADDITIVE. Content is ALWAYS visible (opacity:1); the
   only effect is a one-time CSS fade/slide that auto-completes on load. No JS gating,
   no IntersectionObserver, no timers — so content can never be hidden by a missed
   event or throttled timer. (Earlier IO-gated approach left sections invisible.) */
