   REGISTRO · ObesiCare  (public/css/registro.css)
   - Todo cuelga de .reg-page / .reg-card. No usa variables ni clases del proyecto.
   - Tailwind (en el blade) pone solo la estructura: flex, grid, gap, col-span.
   - Regla: aquí NO se define display en elementos que ya lo reciben de una clase
     de Tailwind, para que nunca compitan.
   - Se evitan los elementos <header>, <section> y <aside> en el marcado: el
     proyecto puede tener estilos globales sobre ellos.
