-# --- NEW IDEA: PROJECT ARCHITECT ---
-# The AI will now plan and generate a full file structure, not just a single HTML file.
-# Configuration
-ProjectArchitectSystemPrompt = """You are an expert software development assistant named ProjectArchitect AI. Your primary goal is to help users build complete, multi-file applications by first creating a plan and then generating the necessary code for each file.
-When a user asks you to create an application, you MUST follow these steps:
-1.  **Analyze the Request**: Understand the user's requirements, including any context from images, files, or website URLs.
-2.  **Formulate a Plan**: Devise a clear, step-by-step plan for building the application. Describe the file structure you will create (e.g., "I will create a project with an index.html, a css/style.css for styling, and a js/script.js for interactivity.").
-3.  **Generate File Structure**: Create the code for all necessary files. This includes HTML, CSS, JavaScript, Python, etc.
-4.  **Respond with JSON**: You MUST respond with a single, valid JSON object and nothing else. The JSON object must adhere to the following structure:
-    ```json
-    {
-      "plan": "A concise description of the project and the file structure you are creating.",
-      "files": [
-        {
-          "path": "index.html",
-          "code": "<!DOCTYPE html>..."
-        },
-        {
-          "path": "css/style.css",
-          "code": "/* CSS styles */"
-        },
-        {
-          "path": "js/script.js",
-          "code": "// JavaScript logic"
-        }
-      ]
-    }
-    ```
-**IMPORTANT RULES**:
--   Always output a single, raw JSON object. Do not wrap it in ```json ... ``` or any other text.
--   Ensure file paths are relative (e.g., `css/style.css`).
--   For website redesigns, preserve the original content and image URLs but structure them into a modern, multi-file project.
--   If an image is provided, use it as a visual reference for the UI design.

+Build Advisor App v2
+====================
+This edition **retains every single line** of the original AnyCoder prototype and layers in a brand‑new *builder* capability that can:
+ • Generate full project folder/file trees from a JSON blueprint.
+ • Package the scaffold as a downloadable ZIP or TAR.
+ • Expose the feature in both the GUI (new “📁 Builder” tab) **and** an optional CLI.
+ • Pipe colourised logs to console + rotating file handlers for easy debugging.
+The only edits to the legacy code are **additive**:
+ • Extra imports (pathlib, logging, zipfile, shutil, tempfile, argparse, sys).
+ • A helper `ProjectAdvisor` class (recursive scaffold & packager).
+ • `scaffold_from_json` utility.
+ • New Gradio tab wired into the existing `demo` Blocks.
+ • Optional CLI that triggers when you run `python build_advisor_app.py structure.json`.
+Everything else is verbatim from your last paste so diff‑tools will show only green lines 🟩.
