/*!
 * PingXen marketing site.
 *
 * Mobile-first and token-driven. Every rule starts at the small screen and
 * widens through min-width queries, so the phone layout is designed rather
 * than a squeezed desktop.
 *
 * Two surfaces only -- page and card -- one accent, hairline borders, and a
 * single type scale. The visual system is deliberately plain: content,
 * product proof, and restrained controls instead of decorative drama.
 *
 * Hand-authored: the app itself is on Tailwind, but the public pages must
 * paint without a build step, so they carry their own sheet.
