/* Arta Cyber Inc. - site.css
   One stylesheet, no preprocessor, no framework. Generated pages live in the
   repo root; the generator is scripts/build_pages.py.

   Rules this file keeps, each because it was broken once:
   - Bronze #A5845E is a GRAPHIC colour on the light ground (3.21:1 fails AA
     for text). Readable bronze on light is --bronze-ink. On navy, bronze is
     fine as text (5.0:1).
   - Container link styles are wrapped in :where() so they carry zero
     specificity and can never repaint a .btn nested inside them (the 1.00:1
     navy-on-navy button of the previous build).
   - No text-transform: uppercase anywhere. No monospace in nav, buttons,
     eyebrows or labels: mono is for protocol names, status values and the
     inside of a sample document.
   - No `transition: all`. Every motion rule is off under
     prefers-reduced-motion (block at the end of the file). */
