- New version generates JSON metadata files with verification codes
- Supports TODO about dynamic randomization

+# TODO: Dynamically randomize verification codes at generation time so fixtures can't be
+#       guessed in advance. This would involve:
+#       1. Generating a random code for each PDF at runtime
+#       2. Writing both PDF and JSON metadata with the randomized code
+#       3. Reading the code from the JSON in tests instead of hard-coding
+#       This ensures the "needle" in the PDF cannot be known before execution.
