/**
 * Solvyr Design Tokens — shared source of truth for all baseline apps.
 *
 * Loaded by shared_assets/partials/head.php BEFORE solvyr.css. Bootstrap 5.3.8
 * remains the layout/grid base; this file adds the design-token layer (a focused
 * port of wfxl/assets/css/tokens.css), aliases the legacy --solvyr-* names so
 * existing markup keeps working, and provides the small set of utility +
 * component classes the shared JS components (Confirm/Modal/FormValidator)
 * and the App Center admin views need.
 *
 * Rule of thumb (matches the WFXL standard): every visual value should read a
 * token via var(--*). Add new tokens here, not hardcoded values in app CSS.
