Polished stainless

• MOPA colours: only from eye-verified test cells, and only on polished stainless. Plain stainless goes black instead.
• Large areas run hotter than small test cells.
• See also Color and the live /color grid data.
• Stainless colour = surface mark: use one layer per colour with the verified pass count, and never copy brass deep-pass stacks. The exception is the verified HD preset below.

High-definition fill black (verified, Hank)

Opt-in via to_ss245 --hd-black (lean version is the default). Very good deep glossy black finish (verified by Hank), but slow.
