Deleted two obsolete documentation files that are no longer needed:
- COLOR-THEME-IMPLEMENTATION.md (204 lines) - Feature complete and documented in code
- prompts/003-implement-htmx-indicators.md (427 lines) - Implementation prompt no longer relevant
These files served their purpose during development but are now redundant with:
- Inline code documentation
- TEST-SUMMARY.md for test coverage
- README.md for user-facing features
- Git history for implementation
