+1. **Real pain, real buyers:** Portfolio drift and risk-limit breaches are daily institutional problems. +2. **Decision speed:** Converts market movement to executable buy/sell guidance in seconds. +3. **Differentiated AI:** Combines forecasting, explainability, and a multi-agent orchestration model. +4. **Trust layer:** Risk analytics + execution cost + tandem timeline create auditability, not black-box outputs. +5. **Demo power:** Interactive architecture, scenario cards, and holding-level drilldown make judges instantly understand value. +6. **Production path:** Deployable on

smart-portfolio-rebalancer +``` +Open http://localhost:8000 + +### Option B: Docker Compose +```bash +cd Flask_py +docker compose up --build +``` + +### Option C: PaaS (Render / Railway / Fly.io /

`PREVIEW_BASE_URL` - base domain for previews (example: `preview.yourdomain.com`). + +Generated preview URL pattern: +```text +https://. +``` +Example: +```text
