TINY AI CALL
Prompt → recipe
One optional structured-output request selects three keys from a closed family enum. It never writes SVG, names, colors, or paths.

A LITTLE ICON GAME / COST-FIRST BY DESIGN
Grow one sharp mark
from one small thought.
A tiny semantic router chooses a bounded visual recipe. The browser owns every path. Cost stays visible; the SVG stays editable.

What should the icon help someone do?
Describe the user job, not the category. “Find quiet places” beats “a map app.”

02 / THE CHEAP PART IS THE SMART PART
At most one model call. Everything else is craft.
The model never draws paths. It chooses meaning; a constrained compiler owns the pixels.
FREE COMPUTE
Recipe → SVG
A deterministic grammar composes bounded object silhouettes. No image model, upload, or per-render AI bill.

FAIL CLOSED
Pixels → proof
The compiler rejects invalid recipes, active content, external resources, and malformed SVG before the user gets the asset.
