   PCW — CSS/proyectos.css
   Estilos SOLO de proyectos.html.

   - Todo usa el prefijo "pcwp-" (PC Wizard Proyectos): no choca con
     style.css, outlet.css ni ninguna otra sección.
   - Reutiliza variables de CSS/style.css: --font-display, --font-body,
     --electric, --sky, --ease, --container, etc.
   - Header, footer, botones (.btn) y "volver arriba" vienen de style.css.
