/* =========================================================================
   OPEN1031 — MARKETING DESIGN LAYER  (_marketing.css)
   Single source of truth for every public marketing page.

   Identity is DERIVED from the brand logo (assets/logo.png):
     - Brand teal  #14B8A6  — the teal arch in the logo
     - Brand navy  #1E3A8A  — the "Open1031" wordmark in the logo
     - Admin/platform chrome  #4f46e5  indigo-600  (app only, never marketing)
     - Dark-slate base  #0f172a / #1e293b / #334155
     - 7 hub color tokens (ID, Sales, Escrow, Purchase, Disbursement, IRS, Reverse)
     - Neela gradient blue → indigo
   ...but this is an EXPANSIVE marketing layer: light/airy surfaces, generous
   whitespace, hero gradients, big type scale, conversion-first. The dark-slate
   in-app chrome is RESERVED for app-preview frames and the compliance band, so
   the marketing site visibly "continues into the product" without feeling like
   a cramped modal.

   BRAND ANCHOR (A4 doctrine):
     - Logo teal  #14B8A6  is the BRAND ACCENT — it appears wherever the logo
       appears, on every surface. It is NOT "the app primary."
     - Logo navy  #1E3A8A  is the wordmark color and headline dark tone.
     - Indigo-600 #4f46e5  is the app admin chrome accent ONLY — it does not
       appear in marketing surfaces.
     - The marketing→app bridge is the shared dark hero/footer band + teal accent;
       when a prospect enters the dark app the brand teal already reads as familiar.

   No build step. No external JS frameworks. Mobile-first; desktop is the
   progressive enhancement. Sticky thumb-zone CTA + tap-driven drawer nav.
