# UI Modernization Plan for Dodgers Stream Theater

## Overview
This comprehensive plan focuses exclusively on UI modernization of the Dodgers streaming platform while maintaining all existing functionality. The modernization follows a systematic approach across 6 phases, transforming the current inline-style interface into a modern, maintainable, and visually appealing application.

---

## Important Info
Always come back and update UI_UPDATE.MD once complete with task and task item. Add any needed notes and if additional tasks are needed for other tasks/sub-tasks/etc add them.

### Version Control Workflow
- Create a meaningful git commit after completing each task/sub-task
- Commit messages should reference the task number and brief description (e.g., "Complete 1.1.1: Inline Styles Extraction")
