Interactive transformer learning labs

Analytical, educational visualisations. Each is an engineering model, not an EMT/CFD simulation or a design calculation.

Scope. These are simplified analytical/educational models used to explain concepts. They are not EMT-type simulations, CFD, or validated design calculations, and they do not claim IEC/IEEE compliance. Each lab declares machine-readable model metadata (model_type / model_version / validation_scope / assumptions / limitations / required_inputs / reference_basis / benchmark_status / engineering_review_status) so the Masterclass and Workbench share the same model identity and validation status. The engineering math is unit-tested (see tests/viz-math.test.js); interactive rendering requires a modern browser and is gated for Learning subscribers where the lab is premium.
