 * 🔴 NO SHADOWS, of any kind, on any element or any text. Separation comes from
 *    color and from space. A soft shadow under a rounded card is the single
 *    clearest tell of a generated page, and the brief rules it out.
 *    checks/check-1a.sh scans for the three CSS properties that make one, so
 *    they are not even named here: a commented-out shadow is a shadow waiting
 *    to be uncommented.
 * 🔴 NO hex colors here. Every color is a token from tokens.css.
 * 🔴 No vh/svh/dvh/lvh: a viewport-height box on a phone jumps when the URL bar
