## What Added GSAP CDN imports to all template compositions and improved project linting to skip template placeholders. ## Why Templates were missing GSAP script imports, causing JavaScript errors when GSAP animations tried to execute. The linter was also incorrectly flagging template placeholder values like `__VIDEO_SRC__` as missing audio sources. ## How - Added `<script src="https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js"></script>` to all composition HTML files - Updated `lintAudioSrcNotFound` function to skip template placeholders matching the pattern `__[A-Z_]+__` - Fixed GSAP animation properties by adding `overwrite: "auto"` to prevent conflicts - Replaced CSS transforms with GSAP `gsap.set()` calls for better animation control - Moved video elements outside timed containers in some templates to avoid nesting issues - Standardized transcript data format to use double quotes for JSON consistency - Added proper timeline initialization with `window.__timelines = window.__timelines || {}` - Enhanced caption styling with overflow handling and max-width constraints ## Test plan - [x] Manual testing performed - [x] Verified GSAP animations work correctly in all templates - [x] Confirmed linter no longer flags template placeholders as errors - [x] Tested video playback and audio synchronization
