Field Guide top tabs are not content types; they are the reader’s big questions. Rules, bets, workflows or features appear as global tags; the tab only decides which big question the page answers.

```text
Field Guide
├─ What is in the app?
├─ How do I use it?
├─ How do I work?
├─ Where is AI going?
├─ What did we promise?
└─ How is it built?
```

Each page carries its own tag panel. The tag panel shows semantics that change reader trust or next decision; metadata such as timestamp and source path stays in lineage.
