   This is the site copy of design/tokens.css: the same file with font paths pointing to ../fonts/.

   Fonts are self-hosted in ../fonts/: nothing loads from Google.
   Orbitron (headings) and Saira (text) are OFL, see ../fonts/OFL-*.txt. Orbitron covers Latin only,
   Saira Latin and Latin Extended. Conthrax, the wordmark's face, is NOT a webfont here: its free
   desktop licence doesn't allow embedding in websites, so it appears only inside the logo files.

   Theme: follows the OS (prefers-color-scheme); force one with <html data-theme="light|dark">. */
