/* DropSet design tokens — the SINGLE source of truth for the whole public site.
 *
 * The landing page and the generated /guide + /programs pages BOTH link this
 * file, so colours, fonts and metrics are defined once and stay in lockstep.
 * Change a colour here and it moves everywhere — never edit palette values in
 * index.html or programs.css again.
 *
 * Note: the two page families still use different component class names
 * (.nav vs .pp-nav etc.), so component CSS lives with each page — but they all
 * read THESE tokens, which is where every drift used to come from. */
