+
+> make a requirements.txt, readme.md, and also remove the seek function completely and reduce the lines of code without hurting stability
+
+Now the `pause()` method — simplify to a plain stop/restart toggle (no seek, no position math):
+
+Now let's add the `_safe` helper to `NaoTeleop` and use it to collapse the repeated try/except boilerplate:
+
+Now the shutdown block — this is where `_safe` pays off the most:
+
+Good — that's stable. Now let's view the final file once more end-to-end to make sure everything reads cleanly before shipping it.
+
+This looks clean and correct. Now let's write the `requirements.txt` and `README.md`.
+
+Good, all confirmed. Now the README:
+
+Now let's copy everything to outputs and present the files:
