Show HN: An atlas of system designs with interactive architecture diagrams

Seems like a match made in heaven :)

Up front: most of the writing is LLM-generated. I picked the topics, set the structure and reviewed the pages, but the prose isn't hand-written.

The architecture diagrams are real React Flow canvases rather than images — they pan, zoom and go fullscreen, and every node is clickable, showing what it's for, its trade-off, and a link to the concept module explaining it. Node colour is by kind across every diagram, so the same colour always means the same thing.

The numbers are interview-grade rather than measured, so treat them as a starting point. Corrections are the most useful thing anyone can send — that's the main reason it's open source.
