®Persia should not exist in World of MATAGI as a folder of beautiful references.
A real research world needs chronology, places, objects, materials, people, routes and disagreements. Achaemenid jewellery should not automatically sit beside Sasanian silk as if centuries and institutions did not separate them.
The moodboard is useful for noticing. The research world is useful for understanding.
This is a MATAGI editorial principle, not a historical claim. Its purpose is to define how the platform should behave when dealing with a civilization that spans long periods and multiple political systems.
The deeper chapter tree should allow visitors to move from era to artifact, artifact to technique, technique to route and route to another culture without losing provenance.
The design benefit is paradoxical: stricter historical structure creates more interesting creative possibilities because the differences are no longer flattened into one vague “Persian” aesthetic.
