Review Comment:
**Suggestion:** `browser` may not be defined if an earlier step raises
before the browser is assigned; calling `browser.close()` unguarded will raise
a NameError/UnboundLocalError — check for the presence of `browser` (and that
it's not None) before calling `.close()`. [null pointer]
**Severity Level:** Minor ⚠️
```suggestion
if "browser" in locals() and browser is not None:

<summary><b>Why it matters? ⭐ </b></summary>
If an exception occurs before browser is assigned, the unguarded
browser.close() will raise an UnboundLocalError/NameError. Checking for
browser's presence (and non-None) before calling close is a minimal, correct
fix for that specific failure mode. It doesn't guard against close() itself
raising, but it resolves the immediate NameError risk.
