/*
 * App-shell tokens that are NOT brand values.
 *
 * app.css previously drew all 24 of its tokens from <brand>-design-system.css, which
 * made the legacy stylesheet a hard dependency of the app shell. Brand-derived values
 * now reference the chassis theme directly (hsl(var(--primary)) and friends, wrapped
 * because the chassis stores HSL triplets rather than hex). What is left below is a
 * spacing scale, an easing, three radii, two tints and two shadows — layout constants
 * that were never brand decisions and that the chassis deliberately does not own.
 *
 * Three are kept as literals rather than remapped, because the nearest chassis value
 * differs visibly and this port is a dependency change, not a redesign:
 *   --radius-lg   12px, where chassis --radius is 10px
 *   --shadow-nav  heavier and wider than the chassis nav shadow
 *   --shadow-blue no chassis equivalent at all
