+
+    <!--
+      HyperFrames composition.tsx.
+
+      Choreography (4 phases, 5.5 seconds total):
+        0.17 – 0.64s   Hero "HyperFrames" + logo asset fade up (opacity + y rise)
+        0.17 – 5.50s   Logo asset rotates ±4° continuously (sine onUpdate)
+        2.17 – 2.62s   Hero shrinks (1 → 0.6) and fades (1 → 0)
+        2.17 – 2.62s   "Build video from HTML" CTA pill pops in with back.out(2) overshoot
+        2.33 – 2.66s   CTA text fades + lifts into place (after container is recognizable)
+        2.83s          Cursor hard-cuts in at off-screen bottom-right
+        2.83 – 3.83s   Cursor approaches via spring path to (W/2 + 120, H/2 + 50)
+        3.83 – 3.98s   Click DOWN: both cursor and CTA compress to scale 0.9 (sync)
+        4.17 – 4.42s   Click UP: both return to scale 1.0 (sync)
+          DOM + GSAP opacity tweens; z-index keeps incoming above outgoing
+        - Press synchronization uses single GSAP target array ["#cta", "#cursor"]
+          to guarantee perfectly identical tween values
+        - Cursor opacity uses a 0.001-second fromTo for hard-cut step change
+        - Logo uses a local static image asset referenced with a plain URL
+        - Breathing rotation only on the logo, not on the whole hero (avoids
+          conflict with the morph exit scale tween)
