/*
 * Search -- the pieces shared by the homepage Search tab (home_search.css) and
 * the results page (search_results.css): design tokens, the two motion
 * primitives, and the person / mind / expression cards.
 *
 * Ported from the designer's prototype (styles.css) with its class names kept
 * byte-identical, like home_hero.css -- see the note at the top of that file for
 * why this is plain CSS and not Tailwind utilities.
 *
 * Do not rely on this file loading before or after its siblings: every
 * stylesheet in this directory is concatenated by `stylesheet_link_tag :app`,
 * so a rule here must win (or lose) on specificity, never on order. Anything a
 * sibling specialises uses a more specific selector.
 */

/* ---------------------------------------------------------------- tokens ---
 * home_hero.css scopes the prototype's colour tokens to .home-hero-root; the
 * results page is not inside it, so it declares the same set on its own root.
 * The motion tokens did not exist in the app at all -- and an undefined var()
 * inside a `transition` shorthand invalidates the whole declaration, so the
 * animation silently disappears instead of falling back.
