   Palette is built from real wavelengths. 633nm is visible red;
   830nm near-infrared is not visible at all - so the invisible
   wavelength becomes the ground, and the visible ones the accent
   ramp. Deliberately NOT neutral-black-plus-one-accent: the base
   carries hue, and the accent is a three-stop spectrum.
   Desktop is the primary canvas; breakpoints collapse downward.
