   mode40.com staging site — layout & components  (v2, high-fidelity)
   Reproduces the LIVE mode40.com design language (extracted from the theme's
   app.min.css): navy + beige + red CTA + teal, the fluid type scale, dark nav
   with teal gradient, radial-gradient proof cards, watermark footer.
   Refined with DOSS-style confident type sizing and the scannable rhythm.
   Built for Chez Koop to reimplement in WordPress.
