/* Ruff Night — the web half of the Neko design system.
 *
 * Palette and rules are lifted from docs/reference/REDESIGN_PLAN.md §6 so the
 * site reads as the same object as the app. Three things carry most of that
 * resemblance and none of them is the colour: the paper grain, the uneven
 * hand-drawn corners, and SF Rounded.
 *
 * Light only, deliberately — the app forces light mode (LESSONS.md §4) and a
 * site that flips to dark next to it would look like a different product.
 * Every colour is therefore stated outright rather than inherited.
