Build a 10-second vertical (1080x1920) motion piece titled 'A morning working with AI assistants' as ONE self-contained index.html (no external assets, no network) that autoplays a looping animation. Dark navy UI windows glow on screen: an assistant collects event posts (counter 1 to 50 reviewed, 17 shortlisted), tracks app points (counter 1,051 to 1,563), runs a pre-publish checklist where green check marks light up one by one, then a cursor clicks an Approve button. Smooth transitions between scenes. No brand names, no people.
