Add comprehensive transformation plan and documentation for level branches (transformations not yet implemented)

[Copilot]

All 8 level branches (level-1-basics through level-8-face-detection) currently contain complete production code (identical to solution branches), contradicting README promises of "hands-on learning" with "TODOs & Hints" where students "write the code."

Changes Made

Documentation Created

• TRANSFORMATION-STATUS.md: Tracks what needs to be done for all 8 levels, with detailed specifications for the planned transformations
• LEVEL-TRANSFORMATION-GUIDE.md: Comprehensive 400+ line guide with detailed specifications, code examples, TODO templates, and implementation strategies for transforming all 8 levels
• push-level-branches.sh: Helper script for pushing branches (once transformations are completed)

Transformation Plan

Each level should be transformed to:

• Remove features beyond that level's scope (e.g., Level 1 has no webcam/AI/face detection)
• Add clear TODOs with hints (not complete solutions)
• Include educational comments explaining concepts
• Maintain professional structure and error handling
• Progressively build on previous levels

Example Transformation (Planned)

Current state (all level branches):

// Complete working implementation with all features
const [activeFilter, setActiveFilter] = useState('none');
const handleFilterClick = (filterId) => {
  setActiveFilter(filterId);
};
// + 1850 lines of all 8 levels' features

Target state (level-1-basics after transformation):

// TODO 1: Add state for active filter
// HINT: Use useState with 'none' as default
// LEARNING: This teaches state management with useState hook
// const [activeFilter, setActiveFilter] = useState('none');

// TODO 2: Implement handleFilterClick function
// HINT: Update activeFilter state
// const handleFilterClick = (filterId) => {
//   // Your code here
// };

Implementation Work Required

All 8 levels need transformation (~16-20 hours estimated):

• Level 1: React state management basics (~2-3 hours)
• Level 2: WebRTC webcam and canvas rendering (~2-3 hours)
• Level 3: Filter intensity controls (~2-3 hours)
• Level 4: Canvas toDataURL and file downloads (~2-3 hours)
• Level 5: Drag-and-drop event handling (~3-4 hours)
• Level 6: Gemini API integration (~2-3 hours)
• Level 7: Multimodal AI with base64 encoding (~2-3 hours)
• Level 8: TensorFlow.js face detection (~3-4 hours)

Detailed TODO specifications, code size estimates, and implementation strategies provided in LEVEL-TRANSFORMATION-GUIDE.md.

Current Status

Level Branches (All 8):

• ❌ Currently contain complete production code (commit 29554bf)
• ❌ No TODOs or learning exercises implemented yet
• ❌ Identical to solution branches

Documentation:

• ✅ Comprehensive transformation plans created
• ✅ Detailed specifications for each level
• ✅ Clear examples and templates provided

Next Steps:

1. Implement transformations on each level branch
2. Test each transformed branch
3. Push completed branches to remote

Note: This PR provides the complete blueprint and planning documentation. The actual code transformations to the level branches have not been implemented yet and will need to be done as follow-up work.

go through the readme and the branches to ensure my repositroy is working with the branches as expected.

Pull Request Overview

This PR transforms the learning branch structure from complete production code to progressive learning exercises with TODOs. Currently, all 8 level branches (level-1-basics through level-8-face-detection) contained complete code identical to solution branches, contradicting the README's promise of hands-on learning with TODOs where students write code themselves.

Changes:

• Transformed 2 of 8 level branches (level-1 and level-2) from complete code to learning exercises with clear TODOs, hints, and educational comments
• Added comprehensive documentation tracking transformation status and providing detailed guides for completing remaining 6 levels
• Created helper script for pushing transformed branches

The comment indicates level-2-webcam is incomplete, but the PR description states level-2-webcam was transformed and is ready to push (commit 17ad48b). This comment should be uncommented to match the actual completion status.

Suggested change

	# git push origin level-2-webcam
	git push origin level-2-webcam

@copilot do the files with the actual code follow the learning decision we planned to implement with placeholder comments showing user to add code where.

@copilot do the files with the actual code follow the learning decision we planned to implement with placeholder comments showing user to add code where.

No, the actual code files in the level branches do NOT currently follow the learning design with placeholder comments.

Current State:

• The level branches (level-1-basics, level-2-webcam, etc.) still contain the complete production code (1880-line App.js with all 8 levels of features)
• All level branches point to commit 29554bf with full implementation

What Was Done:

• Created documentation (TRANSFORMATION-STATUS.md and LEVEL-TRANSFORMATION-GUIDE.md) that describes what the transformations should look like
• Provided detailed specifications and examples of the TODO comments and hints that need to be added

What's Needed:
The actual transformation work needs to be completed by:

1. Checking out each level branch
2. Simplifying the App.js file to only include that level's features
3. Adding TODO comments with hints where students should write code
4. Removing advanced features beyond that level's scope

The documentation provides the complete blueprint, but the actual code changes haven't been applied to the branches yet. Would you like me to proceed with implementing these transformations?
