# Portfolio: Chronicle Portrait Studio Final Polish

The latest updates transform the RPGPortrait studio into a fully-fledged character management tool with a focus on workflow and portability.

## ✨ Highlights

### 👤 Character Identity & Auto-Naming
We've moved beyond generic portraits. You can now define a **Character Name** which acts as the anchor for your creation:
- **🎲 Instant Naming**: A new dice button next to the name field generates thematic fantasy names instantly.
- **Zero Latency**: Powered by a local procedural generator using the `fictional-names` library—no API tokens required.

## Phase 5.1: Model Selection & Fault Diagnostics
- [UI] **Curated Model Dropdowns**: Replaced text inputs with dropdowns for Hugging Face models (Text & Image).
- [UI] **Manual Entry Toggle**: Added a toggle to allow power users to type custom model IDs.
- [UI] **Synthesis Chamber Fault**: Implemented a high-visibility error display in the central canvas for failed generations.
- [Backend] **Restored SD-XL**: Re-added `stabilityai/stable-diffusion-xl-base-1.0` to the default curated list.
- [API] **Config Update**: The `/api/config` endpoint now provides curated lists for the frontend to render dynamically.

## Phase 5: UI/UX Refinement (Finalized)
Successfully migrated engine management to the new **"Configuration"** tab, implemented **"Milk and Cookies"** persistence via `localStorage`, and added the premium **Full-Resolution Lightbox**.

The application is now robust, user-friendly, and ready for deployment! 🚀

### 📥 Named Downloads & Portability
Saving your work is now smarter:
- **Automatic Filenames**: Portraits and data files are saved with your character's name (e.g., `Gildur_portrait_gemini.png`).
- **Embedded Metadata**: Your generation prompts and character names are **embedded directly inside the PNG file**. You can view them in any image viewer with metadata support (like Windows Properties > Details).

### 📋 UI Workflow Improvements
- **Clipboard Sync**: Added native "Copy" buttons to all prompt outputs for quick sharing.
- **Robustness**: Implemented a background "UI Head-Check" to ensure the interface is always stable and error-free.

## 🛠️ Technical Implementation
- **Library**: Switched to `fictional-names` for high-quality, race-specific naming conventions (Tolkien, Viking, etc.).
- **Metadata**: Leveraged `Pillow`'s `PngInfo` to inject context without bloating file size.
- **Modular Fixes**: Refactored the internal logic to ensure the character name propagates from the UI all the way to the final disk write.

**Happy Portrait Crafting!** ⚔️🛡️
