Tyler’s Track Demo Seeder

Sales demo data tool. Reads from production; writes to staging only. Phase 1 scaffold — UI lands in Phase 2.

Phase 1 checklist

✓ Standalone repo, separate from Roasted-Kiwi
✓ Defense-in-depth safety guards (hostname + live DB name)
✓ Two Drizzle clients: prod (read-only) and staging (read-write)
✓ Vendored schema subset for the response-side tables
✓ Tailwind + Tyler’s Track brand colors wired up
