Motion design foundation - timing, easing, enter/exit patterns, accessibility, performance.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

A button hover (1000x/day) = 100ms opacity. An onboarding reveal (1x ever) = 600ms+ full choreography. --- ## Easing Cheat Sheet | Action | Easing | Why | |---|---|---| | Element enters | `ease-out` / spring | Decelerates into resting position (natural arrival) | …

How to install
mdr add athevon/genjutsu/motion-principles@sha256:da789e4612bf6b8eThe line at the top of this page pins the label git:20260928.a0f6e09, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
