 * Canon palette, inverted to a light ground. Plum/Void/Gold/Ivory are unchanged;
 * what changes is which one is the ground. Ivory becomes the surface, Plum becomes
 * the type, Gold stays reserved for geometry and the line only. Canon rules held:
 * gold is never the wordmark, ivory is never pure white, plum is never pure black.
 *
 * Fonts are self-hosted from /fonts. Zero external requests.
 * Proportion is on phi (1.618) rather than ad-hoc pixels.
