-## Phase 2: Targeted Sub-agent Test Framework
-- [~] Task: Design and implement a focused test suite structure in `tests/` specifically for rapid sub-agent GUI verification without full E2E overhead.
-- [ ] Task: Migrate or create at least 3 high-value tests for the main panel rendering paths into this new suite.
-- [ ] Task: Verify the targeted suite runs quickly and reliably.
