   /calculator/banner-creator/ — banner creator, restored 2026-10-11.
   Same page language as /calculator/signature/ (email-signature.css) and
   /calculators/hours/: the theme tokens, a 6% accent tint for surfaces, radii
   22/16/10, the contact-form field recipe, the shared .btn and the
   portfolio.css orbit. Mobile First, every rule scoped under .bc-page.

   Breakpoints: 768px (tablet), 1100px (editor and preview side by side,
   preview sticky), 1200px (orbit shown).
