  "description": "The Apache Software Foundation (ASF) is the vendor-neutral, US 501(c)(3) home of the Apache HTTP Server, Tomcat, Kafka, Spark, Cassandra, Lucene, and over three hundred other top-level open-source projects. The brand voice is institutional, careful, and project-first: the Foundation does not market individual projects; it provides the legal, infrastructure, and trademark umbrella under which independent project communities operate. Visually, Apache is restrained — a red feather mark (Apache Red #D22128), a black wordmark, and a quiet grey supporting palette that defers to the project being read about rather than promoting the Foundation itself.\n",
