/* Sumongo motion — shared styles (sm-motion.css)
 * Everything is scoped under .sm. Tokens fall back to the page's own
 * custom properties (--ink, --muted, --line, --paper, --font) when present.
 * Stage content is sized in em; the stage font-size scales with the
 * component width (container query units), so there is no layout shift.
