Normalize event times to start at 0 in SoundfontMIDIPlayer,
matching the existing fix in SynthesisEngine. Prevents delay
when MIDI files have silence before the first note.

Changed table columns from Title | Duration | Tracks
to Title | Source | Duration - more useful to see where
the MIDI is from (BitMidi, etc.) than track count.

Normalize all event times to start at 0 by finding the earliest
event across all roles and subtracting that offset. Prevents
silence when MIDI files have delayed first notes.

Mobile UX improvements:
- Simplify results table: Title | Duration | Tracks only
- Remove Source (always bitmidi) and Match columns
- Make entire row clickable - no button needed
- Hide Tracks column on mobile (<640px)
- Larger touch targets throughout
Progress bar fixes:
- Larger thumb (20px) for easier iOS touch
- Both 'input' and 'change' events for iOS compatibility
- Larger wrapper height (44px) for comfortable touch
- Scale animation on active thumb
- Better track styling
Table improvements:
- Mobile-responsive padding
- Better cursor states
- Cleaner selected state with accent border

UX Flow: Search → Preview → Generate
Changes:
- Remove 3-column player grid (Tone.js, Soundfont, Custom)
- Keep only Soundfont piano as simple preview
- New section title: "Preview - Review the MIDI before generation"
- Clean horizontal layout: Play | Stop | Volume | Try Next
- This sets up Motif generation as the main event
- Removed Tone.js and EnhancedMIDIPlayer dependencies
- Bundle size reduced from 314KB to 76KB (-238KB!)
Better flow with less confusion. Preview is quick, generation is the focus.

Backend Enhancements:
- Add ParsedMIDIInfo with track analysis and quality issues
- New /api/midi/parse endpoint for MIDI metadata extraction
- Enhanced MIDIService with parseMIDI method
MIDI Preview Player:
- Complete MIDIPlayer class with polyphonic playback
- Basic oscillator mapping (bass=square, mid=triangle, high=sine)
- Lookahead scheduling with proper cleanup
- Automatic stopping when MIDI ends
New UI Flow:
1. Search → Results table with metadata
2. Select MIDI → Shows parsed info (duration, tracks, tempo)
3. Dual transport: Preview Original vs Generate Motif
4. Try Next Result button for easy A/B testing
Search Results Table:
- Title, source, confidence bar, duration, track count
- Quality issues display (short duration, few notes, etc.)
- Auto-select best result, manual selection available
- Visual confidence bars and issue warnings
This makes the project feel "real" - you can now:
- See exactly what MIDI was found
- Verify it's the right song via preview
- Compare original vs procedural synthesis
- Easily try different results

Role Mapping Rewrite:
- Replace naive hard thresholds with scored feature analysis
- Extract comprehensive track features (polyphony, repetition, phrase continuity)
- Add melody vs accompaniment separation logic
- Competitive role allocation with fallback handling
- Support for 6 roles: bass, drone, ostinato, texture, accents, melody
Chord Detection & Polyphony:
- Extract chord events from simultaneous notes (50ms window)
- Add ChordEvent type with multiple pitches
- SynthesisEngine supports both single notes and chords
- Drone/texture layers use chords, others remain monophonic
Feature Extraction:
- medianPitch, pitchRange, noteDensity analysis
- polyphonyRatio calculation via note overlap detection
- repetitionScore using 4-note pattern matching
- phraseContinuity detection via stepwise motion
- register classification (low/mid/high)
This should dramatically improve "sounds like the song" recognition
by using actual musical features instead of arbitrary cutoffs.
