Signature Pad Form
An e-signature step for a lease: read the key terms on a paper sheet, then sign on a pad whose ink thickens when you slow down and thins when you flick, with undo and clear, or switch to typing your name in a handwriting face; the sign button wakes up only when there is enough ink and the box is ticked, then the sheet gets a stamped date.
The mechanic
Velocity-weighted ink: `w = lerp(lastW, clamp(3.6 − v·1.4, 1.1, 3.6), 0.35)` per segment, drawn as short quadratic segments between midpoints so width changes stay smooth; strokes are vectors, so undo, DPR resize and the 'ink' threshold all work from the same data.
