+    <!--
+      HyperFrames composition.tsx.
+
+      Choreography (3 phases, 5 seconds total):
+        0.17 – 0.83s   Title slides down from top: "Build Video With HyperFrames"
+        0.50 – 1.83s   Left card "HTML Composition" enters from left (+16° rotateY)
+        0.83 – 1.83s   Right card "Render Pipeline" enters from right (-16° rotateY)
+        1.67 – 2.17s   Left pill badge "Seekable Timeline" pops in with back.out(1.7)
+        2.00 – 2.50s   Right pill badge "Render Ready" pops in
+        0 – 5.00s      Continuous floating: cards y ±6 px / rotation ±1° (phase-opposed)
+                       Badges y ±5 px (slow shared sine)
+          and .card-tilt (static rotateY + float rotation) so entry and float
+          don't fight on the same alias
+        - All continuous floating consolidated into one shared scene-ticker onUpdate
+          (6 gsap.set calls per frame, batched by the browser)
+        - Phase offset Math.PI between the two cards' floats — opposed breathing
+        - Card images are HyperFrames workflow mockups (no asset files needed)
+        - Ambient dual-glow via two radial-gradients in a single overlay
