/* ==========================================================================
   Pakker — global stylesheet (Parcel redesign)
   --------------------------------------------------------------------------
   Loaded on every page. Holds tokens, reset, shared primitives (container,
   buttons, chips, forms), site header, site footer, Drupal status messages.

   Landing-only layout lives in landing.css.

   Design language: bright product-forward SaaS (unisend.ee / outvio.com
   direction) grounded in Pakker's own app — deep navy ink from the app
   sidebar, parcel-label yellow as the single signature accent, Archivo
   grotesk for everything, IBM Plex Mono for "waybill" labels.

   Tokens are WCAG-AA calibrated against the surfaces they sit on:
     • --c-ink   (#0f1b2d) on white            → 15.9:1
     • --c-muted (#4a576c) on white / mist     →  6.9:1
     • --c-blue  (#1a53c9) on white            →  5.9:1  (links)
     • --c-yellow is a BACKGROUND only — always with ink text on it (11:1);
       never used as text on light surfaces.
