/* Parketti Appel — design tokens
 * Hallmark · theme: custom (tuned) · vibe: "northern daylight, oiled wood, precise"
 * axes: light / roman-serif / warm
 *
 * The thesis: the room is cool, the floor is warm. Paper, ink and rules are tinted
 * toward Nordic daylight (hue ~250–258); the only warmth on the page is the amber
 * accent and the photographs themselves. Nothing competes with the wood.
