+- "context": other feed items (no slots) for cross-source reasoning.
+- "time": current ISO timestamp.
+
+Your output has two fields:
+- "slotFills": map of item ID → slot name → short text (or null if you can't fill it or cannot provide answer). Each item ID appears ONCE with ALL its slots in a single object.
+- "syntheticItems": array of { id, type, text } for new items (briefings, nudges, insights). Only when genuinely useful and when not redundant.
+
+Rules:
+- DO NOT USE EMDASH OR DASH OR ATTEMPT TO USE SYMBOLS TO CIRCUMVENT THIS RULE.
+- One sentence per slot. Two max if absolutely necessary. Be direct.
+- Say "I" not "we."
+- Hedge when inferring. Don't state guesses as facts.
+- Use the week and schedule below to understand when events happen. Match weather data to the correct date.
+- Look for connections across items.
+- Don't pad — return null for slots you can't meaningfully fill, and skip synthetic items if there's nothing useful to add.
+- Never fabricate information not present in the feed. If you don't have data to support a fill, return null.
+- Read each slot's description carefully — it defines when to return null.

+# Welcome to React Router!
+
+A modern, production-ready template for building full-stack React applications using React Router.
+
+[![Open in StackBlitz](https://developer.stackblitz.com/img/open_in_stackblitz.svg)](https://stackblitz.com/github/remix-run/react-router-templates/tree/main/default)
+
+## Features
+
+- 🚀 Server-side rendering
+- ⚡️ Hot Module Replacement (HMR)
+- 📦 Asset bundling and optimization
+- 🔄 Data loading and mutations
+- 🔒 TypeScript by default
+- 🎉 TailwindCSS for styling
+- 📖 [React Router docs](https://reactrouter.com/)
+
+## Getting Started
+
+### Installation
+
+Install the dependencies:
+
+```bash
+npm install
+```
+
+### Development
+
+Start the development server with HMR:
+
+```bash
+npm run dev
+```
+
+Your application will be available at `http://localhost:5173`.
+
+## Building for Production
+
+Create a production build:
+
+```bash
+npm run build
+```
+
+## Deployment
+
+### Docker Deployment
+
+To build and run using Docker:
+
+```bash
+docker build -t my-app .
+
+# Run the container
+docker run -p 3000:3000 my-app
+```
+
+The containerized application can be deployed to any platform that supports Docker, including:
+
+- AWS ECS
+- Google Cloud Run
+- Azure Container Apps
+- Digital Ocean App Platform
+- Fly.io
+- Railway
+
+### DIY Deployment
+
+If you're familiar with deploying Node applications, the built-in app server is production-ready.
+
+Make sure to deploy the output of `npm run build`
+
+```
+├── package.json
+├── package-lock.json (or pnpm-lock.yaml, or bun.lockb)
+├── build/
+│   ├── client/    # Static assets
+│   └── server/    # Server-side code
+```
+
+## Styling
+
+This template comes with [Tailwind CSS](https://tailwindcss.com/) already configured for a simple default starting experience. You can use whatever CSS framework you prefer.
