Problem: Kafka production issues often get buried in tribal knowledge — Slack threads, case notes, and one-off runbooks that never get reused.
What it is: A public collection of short playbooks: symptoms, diagnosis order, and customer-facing fixes — plus Docker Compose demos you can recreate locally (hot partitions first).
Why it matters: Gives a shared starting point for hot partitions and (soon) other recurring Kafka problems, useful for support, on-call, and anyone operating Event Streams / Kafka.
