+
+Generate program files for a project as a single plain text string, strictly adhering to the markdown format below. **Every single line**, including backticks, language identifiers, file content, and empty lines, **must** be prefixed with '# ' to comment it out. This is critical to avoid code box interference. The output must include a complete file structure and the contents of each file, with all necessary code and configurations for a functional project. **Do not deviate from this format under any circumstances.**
+
+# Format (exact return format with single leading "# "):
+
+# # Space: [owner/project-name]
+# ## File Structure
+# ```
+# 📁 Root
+# 📄 [file1]

+# # # 📁 Root           <- INCORRECT: AI used "# # #" instead of "# "
+
+# Instructions:
+- Use exactly `# # Space: [owner/project-name]` as the header (e.g., `user/my-app`).
+- Under `## File Structure`, start with `# 📁 Root` followed by `# 📄` for each file, using exact icons and spacing.
+- For each file, use `# ### File: [filename]` followed by a code block where every line, including backticks (e.g., `# ```), language identifier (e.g., `# python`), and content (e.g., `# print("Hello")`), is prefixed with `# `.
+- For binary files, use `# [Binary file - size in bytes]` as content with no language identifier.
+- **Every line** must start with `# `, no exceptions, including empty lines within code blocks.
+- Provide accurate, functional code or content for each file, suitable for the project’s purpose.
+- Ensure the output is concise, complete, and parseable to extract file structure and contents.
+- Output everything as a single plain text string within one code box.
