 * IMPLEMENTATION_PLAN §4 W13; owner: public web.

 * The only stylesheet on the public site. It is served same-origin (CSP `style-src 'self'`), loads
 * no font or image from a third party, and carries no `@import`. Every verdict is conveyed by a
 * glyph and by words as well as colour, so the palette is presentation only. Colour pairs are
 * chosen for WCAG AA (4.5:1 body text, 3:1 large text and borders) in both schemes.
