   PLANTILLA "¡LO LOGRÉ!" — GRADUACIÓN, logro y orgullo.
   Hoja de estilo AUTOCONTENIDA (NO depende de base.css/temas.css).
   Comparte el contrato de datos del motor (motor.js): mismas clases/IDs/
   data-rol/data-modulo que el resto; cambia el copy y el envoltorio visual.
   Dirección: moderno, celebratorio, no infantil (sirve prepa/universidad).
   Navy + oro + marfil · display contemporáneo (Space Grotesk/Sora) + sans.
   Momento de firma: estallido de confeti + birrete cuya borla se voltea.
   Mobile-first · accesible · sin dependencias.
