Some checks failed
Lint & Test / test (push) Failing after 9s
fix: resolve all 153 ruff lint errors for CI
Auto-fixed 138 unused imports and f-string issues. Manually fixed:
ambiguous variable names (l→layer), availability-check imports using
importlib.util.find_spec, unused Color import, ImagePool forward ref
via TYPE_CHECKING, multi-statement semicolons, and E402 suppression.
