Baseline — before ANY Spectrum theme-review work The last commit before the design-language passes began. Everything the review touched (`ui/docs/theme-review/README.md`) is downstream of this point. Reverting the design language ENTIRELY means going here — but note this is also before the conduit in-memory-new-request work, which is unrelated and was merged in later. To drop the design language while KEEPING that, revert the range pre-theme-review..theme-review-full-scope rather than resetting to this tag. What is downstream of here, in order: theme-review-color-only colour/token pass (no layout) theme-review-full-scope + the layout pass (merge) + 33 commits of conduit work from the other checkout
