Container-based toolkit for circuit design: datasheets, SPICE simulation and KiCad review

Each project here exists twice, generated from one description by tools/makeexamples.py`:

A repository full of good designs proves only that good designs pass. The pair is the evidence: that the rules catch what they claim to catch, and that fixing what they report converges.

Gate acceptance is not production sign-off. These are worked examples, not hardware-validated reference designs. In particular, the FPGA still has decoupling-distance exceptions; signal return paths, application-specific power/thermal budgets and EMC remain engineering review and measurement work.
