Is Infer just referring to inference in this case, or is it some specific noun? Wording seems to imply that Infer is a separate tool or library.

Removed Infer

- **Note:** This is hand-crafted MNIST Classifier (proof-of-concept), and not production trained.This tiny MLP recognizes digits 0, 1, 4, and 7 using manually designed feature detectors.

Nit: Missing a space in "production trained.This..."?

docs/source/pico2_tutorial.md Outdated

- Train real models → Replace hand-crafted weights
- Optimize further → INT8 quantization, pruning
- Deploy fleet → Mass production ready

#### Important Caveats:

- Memory constraints - Models must fit in 520KB SRAM
- Memory constraints - Models must fit in 520KB SRAMn (Pico2)
