Bank 4 batch 4: the AI craft shelf opens on /lab
Ten AI-interface tools land (33 → 43): a token estimator, a streaming-pace lab, a prompt cost calculator, a temperature explainer, a model latency compare, a context planner, a retry timing calculator, a citation format checker, a token budget planner and a motion preference compare. Every tool is local arithmetic, every figure is labelled an estimate or demo value, and the craft shelf renders them all interactive on /lab (docs/enrichment-bank4.md).
No measurement recorded
This entry predates the build report, so it carries no size figure. Saying so is the point: a changelog that quietly omits its numbers reads as if every change were free.
