Specimen library

Patterns, alive and annotated

Each specimen is a working rebuild of a pattern worth learning from: where it's seen, why it's exemplary, what it teaches – and its full source, shown inline. Reconstructed patterns, original code, named provenance; never pixel-copies of anyone's assets.

2 of 21 seeded candidates built (simplest first, deliberately) – the rest arrive with Phase 4, hardest last.
