 # Behaviour:
-#   - .env absent          → copy .env.example to .env, print the path.
-#   - .env present         → no-op (leaves your edits intact), exit 0.
-#   - .env present --force  → overwrite .env from .env.example (backs up to .env.bak).

+#   - .mam.env present --force    → overwrite .mam.env from .mam.env.example (backs up to .mam.env.bak).
+#   - --migrate-legacy           → explicitly rename existing .env to .mam.env if absent.
 #
 # Paths are resolved relative to this script (repo root = parent of deploy/),
