Watch out for
The author announced a bigger v2 for around 2026-10-22, so commands and themes may change; re-run the install line to update. Its study mode learns the style of a design you like but refuses to copy it pixel for pixel. Overlaps with Impeccable (design vocabulary and commands) and oil-ui (several directions side by side); Hallmark ships ready themes and a pass/fail checklist.
