Seeded record from schema API

Generates a single reproducible record matching a field schema (string/int/float/bool/uuid/name/email/enum/date) from a seed. The value-add: structured, schema-driven fixtures that regenerate identically, with deterministic UUIDs and per-field generators. Answers 'Generate a reproducible record for this schema', 'How do I make a deterministic fake object?'.
