+# Drizzle-generated migration snapshots + journal. Regenerated by
+# `drizzle-kit generate`, never hand-edited. Two branches that each add a
+# migration produce divergent snapshots (and journal entries) that CANNOT be
+# meaningfully text-merged — the id/prevId chain and schema state are computed,
+# so a line-level merge yields a snapshot matching no real `generate` run. The
+# only correct resolution is to renumber one migration and regenerate. Hence:
+#   linguist-generated=true  GitHub collapses the huge diff, excludes from stats
+#   -merge                   git refuses to auto-merge and raises a loud conflict
+#                            instead of silently fabricating a bogus snapshot
