Automated pipeline applied 217 type annotations across both UI modules:
- 158 auto -> None return types via AST single-pass
- 25 manual signatures (callbacks, factory methods, complex returns)
- 34 variable type annotations (constants, color tuples, config)
Zero untyped functions/variables remain in either file.
