/**

 * HASH — sistema de registro de conocimiento.
 *
 * Identidad: fondo casi negro + acento lime ácido (paleta de marca:
 * Lime #C7F532, Black #0E0E0E, Graphite #1A1A1A). El logo de HASH son
 * nodos conectados por curvas — ese vocabulario de "nodo + conexión"
 * inspira el indicador de frente activo (punto lime) en vez de un
 * simple fondo gris.
 *
 * Tipografía: Space Grotesk para todo lo que es identidad/estructura
 * (título, frentes, encabezados) — geométrica, con carácter técnico,
 * coherente con un producto que se llama "HASH". Inter para el cuerpo
 * de los mensajes — neutra, no compite, se lee bien en bloques largos.
 *
 * Forma: radios generosos y formas tipo "pill" en los elementos
 * interactivos (frente activo, botón Guardar) como contraste deliberado
 * a la versión anterior, que era toda esquinas rectas de 3-4px.
