🐛 Bug Fixes

• Bidirectional streaming sync — phone→laptop now works
• Add _streamDiff to push/pop/reverse built-ins
• Streaming polish — bind diff, state snapshot, dead code cleanup
• Signal composition — stream derived signals, fix identity check, correct relay routing
• Use explicit /peer/counter channel for streaming-counter
• Integer division + streaming restart
• Component prop signal wrapping + import demo
• When/else parentNode null guard for slot context + match parser boundaries + showcase demo
• Match parser allows container bodies in arms
• Merge duplicate click props + upgrade streaming examples
• For-in parser token mismatch + enhanced step sequencer
• Reactive component props + breakout improvements
• Tetris collision detection — pieces now stack properly
• Collision off-by-one — pieces now stack adjacently
• Keyboard inputs now respect collision — soft drop and hard drop gated on blocked
• Complete collision — checks both top row and bottom cell
• Piece-type aware collision — only T-piece checks bottom cell
• No-overlap rendering — hide foot cell for non-T pieces, render all 20 rows
• I-piece now persists all 4 cells and renders at correct row

🔧 Refactoring

• Type system second pass — deeper unification throughout
• Complete collision system rewrite — decomposed sub-signals

📚 Documentation

• Add STREAM_COMPOSITION.md — full API reference and protocol spec
• Comprehensive documentation update

⚡ Performance

• Streaming core improvements — batched diffs, RTT tracking, relay merging
• Merge same-interval timers + breakout game + beats viewer
