   UniControl Lab - Estilo compartido de herramientas de ingeniería
   (FSM Designer, Logic Designer)

   Traslada la identidad del sitio institucional (site.css v2.2 "Titanium &
   Control Console") a una interfaz de aplicación de pantalla completa:
   - Lienzo claro "titanio", marca azul #0052cc para acciones.
   - Cian #00c6d7 solo sobre superficies oscuras (consola Insight, editor de
     ecuaciones, preset "Consola SCADA" del lienzo).
   - Inter para lo que se lee, JetBrains Mono para lo que se "mide"
     (tags, IDs, ecuaciones, rótulos técnicos).
   - Sin emojis: iconografía Lucide local.
   Tokens idénticos a :root de site.css; no introducir valores nuevos salvo los
   semánticos de herramienta declarados abajo (--danger, --amber-*).
