/* design-tokens.css — the canonical PlatAtlas brand tokens (single source of truth).
 *
 * These are the values landing.css (.landing-root) and the console (:root) already
 * use; this file makes them the SHARED source so a brand change propagates instead
 * of drifting per surface. Adopt it on a surface by mapping the surface's local
 * names to these `--pa-*` tokens (with a literal fallback so a missing file can
 * never break a page), e.g.  --paper: var(--pa-paper, #ede4ce);
 *
 * Light theme only here (the marketing + setup surfaces are light). The console
 * carries its own [data-theme=dark] overrides; when it adopts these tokens it adds
 * a dark block that re-points the same names. Honesty/brand note: ONE accent
 * (McNally highway terra). Never introduce a second accent per surface.
