Glimmer for Rangrez: first-dip colourist (LoRA on Muse Glimmer 30B)

Given a target colour in CIELAB, proposes the first dye recipe (turquoise, fuchsia and lemon yellow reactive dyes, g/L) for the Rangrez self-driving dye lab. Fine-tuned with LoRA (rank 8, 2 epochs; trained on Modal, 1x H100, PEFT) on 2,900 of the lab's recorded dips: each the recipe dipped and the colour SAM 3.1 measured on the dried cloth in a real-looking phone photo. Dataset: TechTush/rangrez-lab-dips.

The dips come from Rangrez's simulator (a hidden dye lot plus realistic photos), not from a physical dye house, and the adapter knows that lot.

First-dip error on 100 held-out targets (CIEDE2000 of the colour the recipe really dyes)
