   ============================================================
   PRINCIPIOS DE DESARROLLO
   ============================================================

   1. SEO (Optimización para buscadores):
      - Todas las páginas deben tener meta tags completos (title, description, keywords)
      - Usar Open Graph y Twitter Cards para redes sociales
      - Incluir Schema.org JSON-LD para datos estructurados
      - Mantener sitemap.xml actualizado
      - Usar URLs canónicas
      - HTML semántico (header, main, article, section, footer)

   2. MOBILE FIRST (Diseño responsivo):
      - Todo el CSS debe funcionar primero en móvil
      - Breakpoints: 768px (tablet), 600px (móvil pequeño)
      - Usar unidades relativas (rem, %, vh/vw)
      - Botones y enlaces con tamaño táctil adecuado (mín. 44px)
      - Imágenes y embeds responsivos (width: 100%)

   3. RENDIMIENTO:
      - Preconnect a Google Fonts
      - loading="lazy" en iframes y imágenes
      - CSS minificado en producción
