/*
  HerMetrics landing site.

  The palette is the app's dark theme (apps/mobile/lib/theme.ts): one accent,
  four phase tints that carry no verdict, and surfaces lifted by tone rather
  than outlined. System fonts only — the page makes no request to anyone but
  Apple's App Store when the badge is tapped, and says so in the footer.
