Pixel Art Technique Coaching with 5.4.L

A short note on using the artifact itself as a teaching surface: make the pixel-art technique visible enough that the model can carry the method forward.

The note

This SVG is drawn by 5.4.L using a new technique to coach the model on pixel art techniques. If you look closely at the images you can see hints of some of the techniques being applied.

The generated SVG artifact carries visible pixel-art technique cues rather than hiding the process behind a finished image.

Why it belongs in the training notes

The interesting part is not just that the output looks like pixel art. It is that the prompt-and-artifact loop is trying to expose a technique the model can reuse: shape boundaries, deliberate blockiness, simplified color transitions, and visible construction hints.
