I want you to build an iOS calorie tracker app. Should have a super clean, minimalist design, very design-forward and aesthetic. Sweat all the tiny details and make everything feel super premium. Make every interaction extremely delightful - you can go so far as to write custom Metal shaders, custom UI components, etc, to make everything fluid, unique, delightful.

The idea I have here is to make it one unified conversational experience. I should be able to page through different days, each of which is a conversation thread with an agent. The agent should have whatever tools it needs to be able to query a nutrition DB or my past history and update the tracked food. It should feel personal and friendly.

I want food entries to be beautiful - it should understand the foods and generate nice, consistent visuals for them, like studio photo looking images with consistent styling. You can use modern small/fast image generation models like Gemini or OpenAI; look it up. I want to be able to somehow zoom out of the thread view and be able to see all my meals in a scrollable timeline where each meal is represented using these images - should feel like a really premium magazine catalog kind of view. Make every transition fluid and delightful, fun gestures, bouncy, Apple-y liquid glass kind of feel to it. Use shader effects to make transitions look special and memorable, to make image generation look good, even to make the chat and token streaming experience unique and fun. Think through the flows to make it usable and show me the information I need without cluttering the screen or making it too technical.

For the most part you should just use your best judgment, not ask me questions, unless you get hard stuck - I want you to interpret this however you want and show me what you are capable of. Build it end to end and verify all the interactions and transitions and functionality in the simulator if you can. Feel free to use the web to download any resources and documentation needed to make this feel great; don't just resort to the boring iOS standards for everything because that's easy. Dig deep and sweat every detail. Have fun!

Start by initializing git, make commits as you go, keep yourself organized with docs so you don't lose track. Write clean, maintainable, modular code.
