/* ═══════════════════════════════════════════
   www.pinroster.com — the marketing site's theme.
   Same palette as the app (dark first, cyan + amber; app.pinroster.com resources/css/app.css)
   and the Deep Water site's layered dark look. Native fonts only: the site loads nothing from
   third parties. Phone first; wider layouts from 720px / 960px.
