/* ============================================================================
 * Kuickr design tokens — the `--kk-*` system (deck-app redesign)
 * ----------------------------------------------------------------------------
 * Design-system library member: kuickr.
 *
 * Source of truth: extracted from docs/prototypes/deck-app/"Kuickr Design
 * Tokens.html" on 2026-06-23. Contract: Kuickr numbered design-system plan
 * docs.
 *
 * This SUPERSEDES the warm-paper `--k-*` vocabulary in
 * app/assets/stylesheets/kuickr.css. During the rebuild both may coexist; new
 * UI references `var(--kk-*)`. Never hard-code hex — reference a token.
 *
 * Light values live in :root; dark overrides apply via [data-theme="dark"]
 * (explicit toggle) — match the prototype, which uses an explicit toggle, not
 * prefers-color-scheme.
