Bug fix:

• routing.py: The _build_response_args function was unconditionally overwriting the explicit status_code parameter with the response class default. Fixed with if/elif so the explicit parameter takes priority.

Typos (8 fixes across docs + source):

• "doesn't known" -> "doesn't know" (https.md)
• Missing "they" (project-generation.md)
• "Environment Variable" -> "Environment Variables" (environment-variables.md)
• "an undefined behavior" -> "undefined behavior" (body.md)
• Two broken Markdown links missing ) (param_functions.py)
• Double space "HTML that" (docs.py)
• Truncated comment "satisfy ty" (datastructures.py)
• Four backticks -> three in two docstrings (oauth2.py)

Test cleanup:

• Removed two leftover print() debug statements
