@copilot our checks have failed. Make sure they succeed:

Run ruff format --check PokemonLibrary/ tests/
...

Fixed in b77e389.

Ruff format: Applied ruff format to PokemonLibrary/terminal.py and PokemonLibrary/ui/panel_mixin.py. These files had pre-existing formatting issues (whitespace/trailing commas) that triggered the CI format check. ruff format --check PokemonLibrary/ tests/ now passes clean.

Robot test failures: I cannot reproduce these locally — all 85 Robot Framework tests pass in my environment (85/85 when running robot atests/). The e2e_tests.robot suite also passes standalone (13/13). The CI workflow does not run Robot Framework tests, only pytest tests/ which passes with 1274/1274. If you're still seeing failures, could you share which textual version is in your environment? The failures look like a timing/event-loop difference across textual versions.
