ruff --select UP007,UP045 --fix converted ~1760 sites across the backend: `Optional[T]` → `T | None`, `Union[X, Y]` → `X | Y`. The remaining module-level alias targets that ruff conservatively skips (BindableFloatInput, ColorList, DeviceConfig) were converted by hand earlier in the pass. black -formatted the result so the wider unions fit cleanly under the 100-char line budget. pyproject.toml now sets [tool.ruff.lint] extend-select = ["UP007", "UP045"] so future legacy imports fire CI on every push. The pre-commit ruff hook was bumped from v0.8.0 -> v0.15.12 to recognise UP045 (split off from UP007 in v0.13).
