Beat 01 · Pattern Interrupt Hook (0%–15%): 0-Second Macro Canvas Cold Open — Immediate visual focal lock before logo bumper.
Beat 02 · Friction & Problem Contrast (15%–40%): Contrasts legacy workflow bottlenecks against libraries.dev's streamlined interface.
Beat 03 · Core Product Proof (40%–80%): High-clarity UI macro capture demonstrating libraries.dev's primary capability in real time.
Beat 04 · Payoff & Call to Action (80%–100%): Brand lockup, launch availability, and URL callout.

Audio & SFX Engineering Profile (EBU R128 Telemetry)

Paced at 122 BPM with an integrated loudness of -14.1 LUFS. Sound design layers mechanical keycap clicks, soft UI whooshes, and sub-bass transition drops synchronized to visual scene cuts.
