 * the query whenever this file changes (see CLAUDE.md "Deploying").
 *
 * Reads tokens already defined per page/track so it never needs its own
 * palette: shared/tokens-consumer.css and shared/tokens-practitioner.css
 * define --keyline/--ease/--font-body; css/tokens.css (Kundali homepage,
 * account.html) defines --border/--font-sans instead and --ease lives in
 * css/home.css. Each property below falls back across both sets.
 *
 * Design rules honoured: no emoji, sentence case, no drop shadows (hairline
 * border only), one easing curve (cubic-bezier(0.16, 1, 0.3, 1)).
