Proportional Animation Values

SHOULD

SHOULD: Keep animation values proportional to the element: dialogs scale from ~0.95–0.8 (never 0), buttons compress to ~0.96 on press (never 0.8).

Animation values should be proportional to the trigger size — don't scale from 0, use subtle values

Bad

Good

Why it matters

Exaggerated animations feel cartoonish and disproportionate. A dialog appearing should scale from 0.95, not 0. A button press should compress to 0.97, not 0.5. Match the animation magnitude to the element's visual size and the interaction's importance.

The rules come from other people's skills and guidelines — Vercel, Rauno Freiberg, @Ibelick, impeccable, Emil Kowalski, Tailwind, RAMS — each one credited on the Sources page. The work here is extraction and wiring: every rule is pulled into one corpus, given a good and a bad example you can operate, a MUST/SHOULD/NEVER rule an agent can paste, and a link back to where it came from.
