/*
  jonmash.com — component styles.

  Ported from jonmash/mash-engineering-website@design/tokens-and-page-system
  (design-system/components.css, MAS-5) on 2026-09-28. Class names and states match
  that contract so the identity strip, header, buttons, and form render identically
  across all three properties. Firm-only components (service-card, boundary-block,
  proof-strip, disclosure-banner) are not included here — this page doesn't use them.
  MAS-12 will replace this copy with a shared package; keep it in sync by hand until then.
