/* Capital — minimalist consumer-fintech UI (rebuild 9e).
 *
 * Scoped under .capnext so it coexists with the legacy capital.css during the
 * rebuild. Reuses the Elkwood/--capital-* design tokens (with safe fallbacks),
 * but lays out a clean, spacious, few-screens consumer app — not the old
 * 12-section terminal. One accent, lots of whitespace, big legible numbers.
