Notes

• New design conversation should happen in Discussions.
• This issue tracks planning and sequencing; implementation can happen in focused child issues/PRs.

Este issue es un seguimiento principal para la planificación de mejoras, no una tarea de implementación, y no especifica archivos, pruebas ni puntos de entrada. Revisa los issues secundarios vinculados y las Discussions para encontrar una asignación concreta; la finalización consiste en implementar un issue secundario específico o actualizar aquí su estado.
