/*
 * Praesens shared design tokens — canonical color / spacing / radius / type.
 *
 * Wave 0 of the 2026-07 UX plan (docs/UX_IMPROVEMENT_PLAN_2026-07.md, item #6).
 * "Literal-for-token": every value below equals the literal the surfaces already
 * used, so adopting this file is a pure-plumbing change with NO visual difference
 * on day one. Later waves reference these tokens instead of hardcoded literals so
 * color work stays consistent and cannot drift again.
 *
 * Two surface themes consume these tokens:
 *   - Dark map hub (app/styles.css) — uses the dark neutral tiers + the shared
 *     status hues.
 *   - Light onboarding pages (app/provision, app/setup, and the edge wizard's
 *     calibration_ui.html) — keep their own :root neutrals but source the shared
 *     brand/status hues from here, including the ONE canonical stop color
 *     (--c-stop-ink) that resolves the previously-undefined / two-different-reds
 *     error color on the light surfaces.
 *
 * Status-hue tint alphas (e.g. rgba(47,179,122,0.18) fills/borders on the map)
 * are intentionally still literals for now; they derive from the solids below and
 * are a later-wave refinement, not part of the Wave 0 foundation.
