/* Huesmith — a grading-suite interface.
 * Layout concept: viewer in the middle, instruments on the right, modules on a bottom page dock like a grading suite.
 * The surround is deliberately neutral grey: colour lives only in the image and the scope traces.

/* Graphite: neutral graphite surfaces, depth from light and shadow, colour only where it means something.
 * Palettes are all neutral greys (a tinted interface would bias colour judgement); they differ in brightness
 * and contrast for eye comfort. Image and scope wells stay dark in every palette. */
