+/**
+ * Refresh the `pricing` article body of the six seeded contract templates to
+ * the live-rate-schedule wording. The per-lane figures (e.g. "USD 400 per
+ * wagon") are now rendered from the LIVE rate config instead of frozen prose,
+ * so any template whose pricing article still carries a hardcoded price token
+ * is rewritten to the current seed text.
+ *
+ * The guard `body ~ '(USD|ETB) [0-9]'` identifies the auto-seeded original
+ * prose (which always quoted a currency + figure) and matches neither an
+ * already-migrated body nor a hand-edited one that adopted the schedule
+ * wording — so admin edits are preserved. Idempotent: after the rewrite the
+ * price token is gone, so a re-run is a no-op. Fresh databases seed the new
+ * text directly (CreateContractTemplates imports the same seed), making this
+ * a targeted backfill for databases seeded before the seed changed.
