+    <title>Scene 01 — Counting Icon Burst</title>
+
+    <!--
+      HyperFrames composition.tsx.
+
+      Choreography (4 phases, 3.5 seconds total):
+        0.00 – 0.17s   Background visible with dark overlay; nothing else
+        0.17 – 0.57s   Four enriched icons enter staggered, clustered at startOffset 0.4
+                       (clock 0.17s · scissors 0.30s · video 0.43s · play 0.57s)
+        0.47 – 1.47s   Counter "0 → 90" with growing font size (0.20W → 0.42W);
+                       icons expand outward from 40% to 100% position
+        0.50 – 2.33s   Camera focus phase: scale 0.92 → 1.0
+        2.33 – 3.50s   Camera push phase: scale 1.0 → 1.08
+        1.27s          Percent symbol pops in with own spring
+
+      Continuous motion (running from t=0, gated by icon visibility):
+        Clock minute hand: linear rotation 420° over 3.5s
+        Scissors: ±15° sine oscillation, period ~1.7s
+        Cutting line: stroke-dashoffset drifts -200 over 3.5s
+        Video record dot: opacity + scale phase-offset sine pulses
+        Play triangle: scale pulse ±8%, period ~2.6s
+          ease + duration (no shared driver needed, just identical timing)
+        - Counter text + number scale are emitted as seek-safe timeline keyframes
+        - Background: local Pexels MP4 plus dark overlay
+        - Per-icon entry uses GSAP fromTo on a nested .icon-entry wrapper
+          so it never overwrites the .icon-pos expansion tween
