/* AXESS pool site.
   Design constraints, deliberate:
   - No JavaScript, no web fonts, no tracking, no cookies.
   - Colour never carries meaning on its own (colourblind-safe: blue/orange/violet,
     never red/green as the only signal).
   - Follows the reader's light/dark and reduced-motion preferences.
   - Body text >= 1rem, line length capped near 70 characters. */
