+# frozen_string_literal: true
+#
+# Improvements over previous version:
+#
+# 1. `frozen_string_literal: true`  — avoids unnecessary String allocations for every literal.
+# 2. `ApplicationRecord.transaction` — atomicity: a failure anywhere rolls the whole seed back.
+# 3. `delete_all` over `destroy_all` — skips ActiveRecord callbacks and validations; orders of
+#    magnitude faster for bulk teardown where those side-effects are irrelevant.
+# 4. Ordered `delete_all` respects FK constraints without disabling them.
+# 5. `tag_map` as a local variable — constants defined in seed.rb leak into the global namespace
+#    and raise "already initialised" warnings on every subsequent `db:seed` run.
+# 6. `days_ago.days.ago.to_date` — idiomatic Rails; reads like English and handles DST correctly.
+# 7. `PostTag.insert_all!` — collapses N individual INSERT statements into one, which is the
+#    single biggest query-count win available in this file.
