/* ========================================================================== Pearto public reference design system -------------------------------------------------------------------------- Derived from the 8 supplied reference images (64 panels). It is loaded ONLY by templates/base.html, which the staff control center does not extend (templates/staff/base.html is standalone with its own ), so nothing in this file can reach /staff/ or /django-admin/. It ADDS to the token system in app.css rather than overriding it. No existing token is redefined, so any surface that does not opt into a .ref-* class is unchanged. Where the reference differs most from what Pearto already had: - a warm paper canvas instead of a cool grey one - larger card radii and almost no shadow (borders do the work) - tinted pastel panels for results rather than white-on-white - a photographic-feeling hero band (built from CSS, not licensed imagery) ========================================================================== */ :root { /* Warm paper rather than the cool --ink-50.
