## File Reviews

### index.html

**Status**: COMPLIANT

**Issues Found**:

- None. Correctly uses `data-composition-id`, `data-width`, `data-height`, and `data-duration`. Registers `master` timeline.

### compositions/intro.html

**Status**: COMPLIANT

**Issues Found**:

- None. Correctly uses `<template>`, registers `intro` timeline, and has required attributes.

### compositions/captions.html

**Status**: HAS_ISSUES

**Issues Found**:

- **Line 95**: Attempting to set `data-duration` via script. This should be a static attribute on the composition root (Line 2).
- **Line 2**: `data-duration="30"` is set, but the script calculates a different duration. These should be synchronized manually in the HTML.

### compositions/graphics.html

**Status**: COMPLIANT

**Issues Found**:

- **Line 135**: Redundant GSAP script import inside a composition template. While not a schema violation, it's unnecessary as GSAP is loaded in `index.html`.
