Sheet 19

Motion

Motion is proof happening — the check draws once, settles, and stays. No bounce, no spin, no loops: trust moves deliberately, then stands still.

The rule

Draw once, settle, hold — nothing bounces, nothing loops.

THE VERIFICATION MOMENT — 600 MS, FOUR FRAMES 0 ms the R waits 180 ms short arm lands 420 ms long arm sweeps 600 ms settled — held one gesture · left to right · never reversed EASING — cubic-bezier(0.2, 0, 0, 1) time → fast in, calm landing DURATIONS 150 ms micro — hover, toggle, fade 300 ms standard — panels, reveals 600 ms signature — the check draw PREFERS-REDUCED-MOTION Every draw becomes a 150 ms fade. No exceptions, no “tasteful” overrides — respecting the setting is a trust move. ✓ verified ≠ animated rule draw once · settle · hold tokens 150 · 300 · 600 · bezier(.2,0,0,1)
