/* ============================================================
 *  ZING PLATFORM — shared design system ("cool classic")
 *  SINGLE SOURCE OF TRUTH: Zing Platform/_shared/platform.css
 *  Copied into each app (public/ or src/) by sync-shared.sh.
 *  Edit THIS file only — per-app copies are overwritten on sync.
 *
 *  Decided 2026-07-07: this replaces the retired "Canvas" system.
 *  Tokens are UN-prefixed (apps already use these var names).
 *  Components are .zp-* so they never collide with an app's
 *  existing classes; apps migrate to them screen by screen.
 *
 *  Per-app accent: an app may set --accent in its own stylesheet
 *  (e.g. Grow green #2f8f5b). It colours the nav active state and
 *  the app mark ONLY. Everything else stays identical.
 * ============================================================ */
