/* paragbatavia.com — "Dossier" redesign
   Drop-in starting point for src/css/site.css.

   This file contains ONLY the tokens, resets, and the global chrome
   (header, footer, links, focus, typography primitives). Build the page
   sections on top of it following design_handoff_site_redesign/README.md.

   Rules that hold everywhere in this design:
     - border-radius is always 0
     - borders are always 1px solid
     - there are no box-shadows except the two inset underline treatments
     - there are no gradients, no keyframes, no entrance animation
