   Estilo "shadcn/ui" para la app (https://ui.shadcn.com, tema neutral).

   shadcn/ui es un catalogo de componentes de React + Tailwind, y esta app no usa
   ninguno de los dos: no se puede instalar tal cual. Lo que se hace aca es copiar su
   DISEÑO -- los mismos colores (tema neutral), radios, bordes finos, sombras sutiles,
   anillo de foco de 3px y estados hover/disabled -- sobre las clases que la app ya tiene
   (.btn-primary, .field, .chip, .check-box, ...), sin tocar ningun layout.

   Se carga DESPUES de styles.css y no cambia tamaños de pantallas: para sacar este
   estilo alcanza con quitar el <link> de index.html. La fuente (Manrope) y los
   titulos en mayusculas son de la marca y se conservan.

   Mapeo de componentes shadcn -> clases de la app:
     Button (default / outline / destructive) .btn-primary / .btn-outline / .btn-outline.danger
     Input, Textarea, Select ................. .field, .suffix-field, select
     Checkbox ................................ .check-box
     Toggle Group / Tabs ..................... .chip, .option-box, .status-pill
     Slider .................................. input[type="range"]
     Item / Card ............................. .menu-item, .sol-card
     Dialog / Alert Dialog ................... el Modal (modal.js, .vm-*)
