/* Tiphaine de Bodman — the design system.
 *
 * The palette is taken from the Birds Carpet, measured off the photograph
 * rather than guessed: the rug was sampled by hue, giving ink #22242B from the
 * border and the birds, sienna #A15018 from the large leaves, gold #BF943D
 * from the small ones, and a wool ground that reads #DCDBDC under the
 * photographer's light.
 *
 * Two of those are adjusted for screen and the reason is worth writing down.
 * A photograph of wool under warm light desaturates: the ground is warm cream
 * in the room and neutral grey in the file, and the gold leaves are brighter
 * than a camera records them. So `--paper` is warmed back to #F4F0E8 and the
 * gold lifted to #D9A33A. The ink and the sienna are used as measured.
 *
 * One brand, so one theme — but the mechanism that carried three for Naturabuy
 * is kept, because four apps are coming and a per-app accent is then a
 * one-line change rather than a second stylesheet.
 *
 * Public Sans is served from static/fonts as a @font-face rather than from a
 * CDN: these apps sit behind an authenticating ingress, and a webfont request
 * that leaves the network leaks which app an authenticated user is looking at.
