/* Kombyno landing — Act 5, "how it works" + the invite (prefix a5-).
   Part one (steps) stays on the page's ink background. Part two (the band)
   is the page's one tonal flip to light; every colour inside .a5-band is
   scoped to that element via [data-kb="light"] and uses raw --kb-* palette
   tokens (cream/ink/teal/coral) rather than the semantic --kb-bg/--kb-text
   roles, so it renders light regardless of the page's dark data-theme. */
