/*
 * Connecting Startup — v3 "plano técnico"
 * ---------------------------------------------------------------------------
 * El vernáculo de la ingeniería de sistemas: rejilla de delineación visible,
 * líneas de cota, llamadas numeradas, anotación en monoespaciada y cuadro de
 * rotulación. Un plano ES un diagrama de conexiones, así que la idea de las
 * cuatro conexiones vive aquí de forma nativa.
 *
 * Reglas:
 *   1. Radio cero y filetes de 2px. Las sombras son duras, sin desenfoque.
 *   2. La monoespaciada es para datos reales (códigos, cifras, referencias),
 *      nunca para decorar.
 *   3. El rojo de revisión marca el circuito vivo. Nada más.
