Design Feedback Aggregator

## Setup Guide
1. **Webhook**: Configure your form tool (Typeform, Tally, etc.) to POST to this webhook URL.
2. **Google Sheets**: Create a sheet with columns: `Project`, `Designer`, `Feedback`, `Sentiment`, `Date`.
3. **Slack**: Connect your Slack account to notify the team.
4. **OpenAI**: Add your API key to analyze sentiment.

**Workflow Logic**:
- Receives feedback via Webhook.
- Analyzes sentiment using AI.
- Routes based on sentiment (Positive vs. Negative).
- Aggregates negative feedback into a digest.
- Saves everything to Google Sheets.
