Cryptographic ID Seeder for Mock Databases
Pre-configured for fixture and seed-file workflows: a usr_ prefix, hyphens stripped for compact column values, and 50 IDs per batch — the shape you paste straight into mock data. Swap the prefix per table (ord_, inv_, sess_) and regenerate; every ID still comes from the browser’s secure random source, so seeds never collide across batches.
runs 100% in your browser — secure entropy, zero transmission
