/**
 * DesignIntent — versioned, validated user requirements model.
 *
 * A DesignIntent captures what the user wants to build at a high level:
 * project goal, functional blocks, electrical requirements, power rails,
 * mechanical constraints, manufacturing intent, and safety/regulatory notes.
 *
 * DesignIntent is the **input** to the compile pipeline.  It is compiled
 * into a CircuitIR (the validated, machine-readable source of truth) which
 * downstream EasyEDA tools consume.
