/*
 * Deep Water design tokens. Light only — there is no dark mode.
 *
 * Adapted from UnlikeOtherAI's "Apple-like portal" design system: one blue on
 * a grey-on-white ramp, pill-shaped controls, flat 16px cards with a 1px
 * border, shadows only on things that float. See docs/ui/admin-design-spec.md.
 *
 * The single source of every value, shared by the admin console (imported by
 * admin/src/index.css, named by admin/tailwind.config.js) and the public
 * research archive (copied to /design-tokens.css by web/scripts/build.mjs).
 * Components read them as var(--…).
