   ReelEstate — sistema de diseño (oct 2026)
   Blanco y negro como el logo; el color lo ponen las fotos y los videos.
   Oscuro por defecto, claro a elección (data-theme en <html>, ver prefs.js).
   Lo usan la landing y las páginas legales; la app lo adopta pantalla por
   pantalla. El showroom público sigue con tokens.css hasta que se decida.
