 ## Performance Guidelines
 - Image resizing (LANCZOS resampling) is the primary bottleneck (~65% of CPU time)

-**Test Coverage Reports:**
-- Run with coverage (excluding parallel tests): `uv run pytest --cov=cdisplayagain --cov-report=term -q -k "not parallel"`
-- Check missing lines: `uv run pytest --cov=cdisplayagain --cov-report=term-missing -k "not parallel"`

-**Known Issues:**
-- Test suite crashes with full coverage run due to parallel worker threads in `test_parallel_workers.py` and `test_benchmark_parallel.py` not being properly stopped. These tests create infinite-loop threads that survive test teardown and cause coverage collection to crash. Fix requires adding proper thread cleanup to `ImageWorker`.
