# Theater.js Programmatic Motion Design

Creates choreographed multi-element web animations with Theater.js: Sheets, Objects, Props, Keyframes, sequence playback, and real-time visual scrubbing extension.

## When to Invoke
Invoke this skill whenever you need to:
- orchestrate animation theaterjs
- use theater.js studio
- animate multiple objects synchronized

## Execution SOP & Rules
1. Initialize projects using const project = getProject('ProjectName', { state: projectState }).
2. Create sheet actors with sheet.object('Title', { opacity: types.number(1), y: types.number(0) }).
3. Use sheet.sequence.play({ iterationCount: 1 }) to trigger scripted animations.
4. Load @theater/studio dynamically in development only; omit studio bundle from production builds.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
