Resources

Looking for something specific? It's probably already got a home:

• Libraries & tools → Ecosystem (official + community-maintained, added via PR)
• Talks & conference recordings → Events (Functional Scala, ZIO World, Zymposiums)
• API docs → API reference (the Scaladoc of every ZIO module)
