squiggle-draw-on

Purpose

Render a hand-drawn-feeling SVG line that animates as if being drawn live — used for underlines under headlines, arrow callouts, accent squiggles around logo lockups, or motion-line trails behind a traveling element-handoff object.

The visual signal of "not perfectly vector" is a critical anti-AI tell across reference videos. Sterile straight lines look algorithmic; squiggles with light per-vertex jitter feel human.
