简介
Explains the CAP theorem through an animated distributed system with 3 nodes. A network partition is triggered, and the animation shows the trade-off: choosing CP sacrifices availability while choosing AP allows divergence. Real-world systems are labeled with their CAP classification.

CAP Theorem
Description
Explains the CAP theorem through an animated distributed system with 3 nodes. A network partition is triggered, and the animation shows the trade-off: choosing CP sacrifices availability while choosing AP allows divergence. Real-world systems are labeled with their CAP classification.

| 1 | Intro | 3s | Title displayed |
| 2 | CAP Triangle | 6s | Animated triangle showing Consistency, Availability, Partition Tolerance |
| 3 | System Setup | 4s | 3-node distributed system shown with links |
| 4 | Network Partition | 5s | Link between nodes breaks (shown as red X) |
| 5 | CP Choice | 8s | System rejects writes; nodes show same value; "consistent" |
| 6 | AP Choice | 8s | Writes accepted; nodes diverge (different values); "available" |
| 7 | Real Systems | 8s | Label HBase=CP, Cassandra=AP, Zookeeper=CP, DynamoDB=AP |

Notes
- Network partition shown as a jagged break in the connecting line
- CP choice: nodes go gray/locked, error message shown for writes
- AP choice: nodes show divergent values (v=1 vs v=2) with different colors
- Real system labels styled as code-like tags
