Promo video: explain Beckon

In this folder are four reference screenshots (reference-1.png through reference-4.png) of heybeckon.ai — Beckon, a voice-driven agentic workspace for Mac.

Create a fantastic Remotion promo video (1920x1080, about 30 seconds) that explains what Beckon is, how it works, and its key features — recreating the app and site's look and feel from the screenshots as animated React scenes. Do not embed the raw screenshots as full-frame images; rebuild the UI as components and animate them.

Rules:
- Scaffold a Remotion project right here and render the final MP4 yourself, with no human intervention — "done" means a rendered MP4 exists on disk.
- Remotion and its standard npm dependencies are allowed; no other external assets (no downloaded fonts, images, or stock footage).
- Design, copywriting, pacing, and motion are yours.

One shot: this single turn is the whole run.
