+
+    <!--
+      HyperFrames composition.tsx.
+
+      Choreography (4 phases, 7.5 seconds total):
+        0.00 – 0.67s   Typewriter reveals "HyperFrames turns" (3 → 17 chars)
+        1.67 – 2.22s   Ticker scrolls: HTML → motion
+        3.33 – 3.88s   Ticker scrolls: motion → video
+        4.60 – 5.45s   Logo enters from offscreen-right with rotation + scale impact
+                       Text group pushed left + fades (40-50% of hero duration)
+        6.60 – 7.50s   Logo breathes (dual-frequency sine onUpdate, multiplicative on 1.3 scale)
+          tuned to 40-50% of hero duration so the impact reads as causal
+        - Breathing uses Form 2 (onUpdate) so it multiplies onto the 1.3 final scale,
+          not overwrites it (Form 1 yoyo would undo the impact)
+        - Two breathing periods (1.0s scale, 1.33s rotation) for organic feel
+        - Logo uses a local static image asset referenced with a plain URL
