+# =============================================================================
+# Use this when the migration partially failed and you need a clean slate.
+# Safe to run multiple times — it always starts fresh.

+# What this does:
+#   1. Drops and recreates the public schema (wipes all tables)
+#   2. Runs the migration script (recreates schema + copies SQLite data)

+# Usage:
