Judge notes: Translation is fluent, natural, and marketing-appropriate with all HTML/links preserved correctly; "Descubre" is a smart idiomatic upgrade over a literal "Compra" — nearly flawless with no meaningful weaknesses.

<h1>Bienvenido a BrightCart</h1><p>Compra las mejores ofertas en electrónica, artículos para el hogar y moda. ¡Regístrate hoy y obtén 15% de descuento en tu primer pedido!</p><a href="/signup">Crea tu cuenta gratis</a>
Judge notes: The translation is accurate, natural, and production-ready with all HTML/URLs preserved; the only marginal nitpick is "Compra" could optionally be "Descubre" for a more marketing-polished tone, but this is a matter of style, not error.
GPT-5.4 8/10 
<h1>Bienvenido a BrightCart</h1><p>Compra las mejores ofertas en electrónicos, artículos para el hogar y moda. ¡Regístrate hoy y obtén un 15% de descuento en tu primera compra!</p><a href="/signup">Crea tu cuenta gratis</a>
Judge notes: The translation is accurate, fluent, and production-ready with all HTML preserved correctly, but "Compra las mejores ofertas" slightly shifts "latest deals" (últimas ofertas/promociones) to "best deals," which is a minor but real semantic drift from the source.
Gemini 2.5 Pro 9/10 
<h1>Te damos la bienvenida a BrightCart</h1><p>Descubre las últimas ofertas en electrónicos, artículos para el hogar y moda. ¡Regístrate hoy y obtén un 15% de descuento en tu primera compra!</p><a href="/signup">Crea tu cuenta gratis</a>
Judge notes: Translation is natural, fluent, marketing-appropriate Latin American Spanish with all HTML/URLs preserved perfectly — the only microscopic nitpick is "Te damos la bienvenida" vs. the slightly more common "Bienvenido/a a," but both are correct and the chosen form is arguably warmer.
Grok 4.1 Fast Reasoning 8/10 
<h1>¡Bienvenido a BrightCart!</h1><p>¡Aprovecha las últimas ofertas en electrónicos, artículos para el hogar y moda! Regístrate hoy y obtén 15% de descuento en tu primera compra.</p><a href="/signup">Crea tu cuenta gratis</a>
Judge notes: The translation is fluent, natural, and preserves all HTML/URLs correctly, but the added exclamation mark in the h1 (not in the original) and the period change from "!" to "." in the paragraph are minor unsolicited structural alterations that would warrant review before production use.
