/**
 * FFToolbox shared UI foundations (fft-ui.css)
 * ============================================
 * Workplan: docs/wip/20260930/WORKPLAN_SK_HEADSHOTS_AND_TOP25_RESPONSIVE_POLISH.md (Phase U0)
 *
 * Loaded on every page by includes/NewHeaderTest.php (PHP pages include it
 * directly; ColdFusion pages pull it in via includes/header.cfm ->
 * includes/NewMenuHeader.cfm -> cfhttp NewHeaderTest.php) and by the legacy
 * includes/header.php. It loads AFTER FftNewMenu.css, i.e. last in the cascade.
 *
 * RULES FOR THIS FILE
 *  - Opt-in only. Every selector is scoped to an .fft-* class (or to the
 *    header login button). Nothing here restyles an existing page until the
 *    page adds the class.
 *  - Never target ad/monetization containers (#side-b, .skyscraper, .sky,
 *    .ad, .advertisement, [id*=usmg_ad], [id*=google_ads], .logoBar, ...).
 *  - Breakpoint scale (use ONLY these values in new rules):
 *        390px   small phone
 *        560px   large phone  (card rows, scrolling toolbar)
 *        768px   tablet portrait (44px row targets)
 *        1024px  tablet landscape / small laptop
 *        1280px  desktop
 *  - Motion: 150-200ms transitions; all motion is disabled under
 *    prefers-reduced-motion: reduce (bottom of file).
