/* Cream design tokens: the single definition of the brand.
 *
 * These values are canonical and are documented in DESIGN.md. The marketing
 * website links this file directly. The consoles still embed their own :root
 * block (they predate this file); where they differ, this file wins and the
 * console is the thing to fix.
 *
 * Nothing here describes layout. Tokens only, so any surface can adopt the
 * file without inheriting another surface's opinions.
 *
 * THREE VALUES WERE LIFTED ON 2026-08-30, and the reason is written here
 * because a brand colour should never move without one. design-a11y-test.js
 * computes every text-on-ground contrast ratio from this file and measured
 * three of them under the WCAG AA floor of 4.5:1 for small text, on the live
 * public site: --ink-faint at 4.4134, --t-self at 4.4520, --below at 4.4664.
 * Four browser reviews had missed all three, because the eye cannot judge a
 * ratio and arithmetic can. Each was raised by the smallest step in HLS that
 * clears the floor with a little margin, holding hue and saturation exactly,
 * so the palette reads as itself: a total shift of 7 to 10 points out of 765
 * per colour. The old values are recorded beside the new ones so the change
 * is auditable rather than silent.
