 * Mismo sistema visual que el producto (web/src/styles.css): papel, tinta y
 * tres acentos (pine bien, amber atención, clay mal). La paleta no se toca.
 * Tres familias con roles fijos: Newsreader para títulos y citas, IBM Plex
 * Mono solo para datos y etiquetas cortas (nunca una oración) y la sans del
 * sistema para el cuerpo. Ningún texto por debajo de 11px.
 *
 * Las réplicas de la interfaz (.mock) están hechas en HTML y CSS con los
 * mismos nombres de clase del producto (.post, .said, .face, .pulse, .st...).
