   Brand-agnostic component layer for Stripe-grade marketing pages.
   Values calibrated against live captures of stripe.com, linear.app,
   vercel.com, attio.com and ramp.com (see references/signature-moves.md).

   HOW TO THEME: change only the "Brand inputs" block. Everything else
   derives from it. Dark sections: add data-theme="dark" to any element.
