## TL;DR

Maya civilization is known for writing, calendar systems, mathematics, astronomy, cities, and architecture in Mesoamerica. This repair removes duplicate broad facts and replaces future book metadata with Britannica, UNESCO, and Smithsonian evidence.

## Core Explanation

The public facts now focus on the writing/calendar tradition, Chichen-Itza as a major site, and the interlocking calendar cycles. Claims about collapse causes and exact calendar precision are left out of the sampled public claim set.
