// Regression test: brand logo (and all /brand-logos/... images) must load
// through Next.js Image optimizer on the tuxedo storefront.
//
// Pre-fix state:
//   GET https://water.tuxedocorn.com/_next/image?url=%2Fbrand-logos%2F64294306-...%2Flogo.png
//     → HTTP 400, body: "url parameter is not allowed"
//
// Post-fix expectation:
//   → HTTP 200, content-type: image/* and non-empty body
//
// Root cause identified: Next.js standalone build is missing the
// `.next/standalone/public/` folder. The deploy workflow copies
// `.next/static` but not `public/`. Without `public/` in standalone, the
// image optimizer can't resolve local-relative URLs.
