PRESET 00

Welcome. — pick a preset to load a shader, or just start typing GLSL in the Image tab. Auto-probe is on; click ⌖ then a pixel and every named local lights up in the watch panel.

WebGL2 · Image + Buffer A–D MRT passes · GPU-printf via second-draw into an RGBA32F probe FBO · async readback with fenceSync · 240-frame history ring · dataflow DAG built from the source · two-program differential.

Pair with the AArch64 lab for the GLSL ↔ machine-code side of the same story.
