/* site.css - A Byte of Everything, the studio website. The only stylesheet.
   The studio's own look: warm paper, one ultramarine, Space Grotesk for display
   (self-hosted, fonts/OFL.txt) and the system face for reading. The mark is the
   letter A as one byte, 0100 0001, drawn from eight cells. Each game card wears
   that game's own colours, taken from its own website and app.
   No script anywhere and no inline style: the CSP is style-src 'self'. Motion is
   CSS only and stops under prefers-reduced-motion. */
