 * PLACEHOLDER PALETTE. The design desk's palette replaces this block and the
 * :root values below, wholesale. Nothing here is a design decision; it is the
 * minimum needed to read the pages while the real palette is drafted.
 *
 * One accent, used only for links, focus rings and buttons. Never body text.
 * Every text-on-surface pair below is checked by tests/test_contrast.py,
 * which parses the JSON between the two markers. Keep the markers.
