/* Calculator lead funnel (js/plan-funnel.js), 2026-09-30.
   The app's onboarding cards, hosted on the website: the same palette, type and
   motion as the app's standardised cards (obStd.css) and area picker
   (AreaPickerCard.tsx). A copy; nothing here is loaded from or changes the app.
   Barlow Condensed 700 headings, DM Sans body, JetBrains Mono labels and figures,
   #00FF88 on #0A0A0F. Full screen on phones, a phone-sized card above 640px. */
