   IDENTIDAD EKIPOS (Identidad de marca/Manual de marca EKIPOS)
   El azul manda; verde, violeta y ámbar son acentos, nunca fondos grandes.
   Es la paleta del producto, no la de un cliente: la marca de cada empresa
   vive en sus logos y en sus reportes.

   Modo claro y oscuro: todo color de la interfaz sale de estos tokens.
   `lib/theme.ts` pone data-theme="dark" en <html>; nada más cambia.
