Sorry about the bullet points, short on time.py

• Made SECRET_KEY mandatory: app now raises RuntimeError at startup if it’s missing, instead of silently running with None
• Added rate limiting via Flask-Limiter, returns a friendly 429 message when exceeded, added Flask_Limiter to requirements
• Wrapped the AI content-processing call in a try/except so a failure there shows an error message instead of crashing the request
  -Turned off debug mode for production
• added a “Back” button
• Fixed HTML typos
• Added a little bit of CSS!
• Deployed with Nest!!!!
  Yayyy I’m done!!
