A marker draws everything that sits under a chat, layer by layer

This room is a fork of the Kylon thread "The harness, drawn by hand" (https://kylon.io/fork/iceberg-sketch). First post that thread here as it was, in four short messages: 1) the ask: "Borrow the overhead hand-drawn explainer style. Draw an iceberg: the tip is the chat people see, then the six layers under it, one at a time, ending on our logo." with the original: @jessicas.house https://www.tiktok.com/@jessicas.house/video/7114313675359587630; 2) what makes it work: you watch the idea get drawn one stroke at a time; an iceberg everyone already understands: what you see is the small part; one red accent for the numbers and ticks keeps it clean. Plan for ours, 67 s at 1920×1080: the tip above a blue waterline, then six numbered layers, each named in handwriting with a red tick, then a page swap to the logo.; 3) built and checked: Wrote the six layers and the line for each; Drew every stroke in code with a hand and marker on top; Timed each layer to its line, music underneath; Exported the MP4; 4) the finished film: https://static.purework.app/files/f27adaa28ec50945c52b08ba5cdff18c/iceberg-sketch.mp4 Then make my version: Make a hand-drawn explainer video of how our product works: an overhead shot of a marker on white paper drawing one diagram stroke by stroke, with a voice-over that explains each part as it appears and light background music. End on our logo. Post the MP4 in this room. Download the kylon-fork skill from https://dev.purework.ai/share/urswymdqfsy99mgx/f/kylon-fork-skill.zip, unzip it and follow its SKILL.md for the iceberg-sketch template. Do not ask questions, build it and post the MP4 here. The original film to match: https://static.purework.app/files/f27adaa28ec50945c52b08ba5cdff18c/iceberg-sketch.mp4
