/**
 * Atomic Ink Portfolio

 * The design language is four-colour process printing: ink linework, paper
 * white, and cyan/magenta/yellow plates. Offset shadows are coloured rather
 * than black, so a card reads as a slightly misregistered print plate.
 *
 * Palette arrives as custom properties from plugin settings, so nothing here
 * needs recompiling when the colours change.
