Key color fix: - Previous offset put D# major at green (~150°) instead of orange (~30°) - New offset: (position + 8) * 30° so position 5 (D#/Eb) = 390° mod 360 = 30° orange - Position 8 (C) = 480° mod 360 = 120° green. Adjacent positions = adjacent hues. BPM color fix: - Previous wrap-around math went blue→purple→red, missing cyan/green/yellow/orange - New: simple linear interpolation 240° → 0° (long way: 240→180→120→60→0) - 60 BPM = blue (240°), 120 BPM = green (120°), 180 BPM = red (0°) Badge text cleanup: - BPM: just the number (e.g., '140'), no 'BPM' text. Tooltip shows full value. - Key: shortened format — 'D#m' for minor, 'D#' for major. Unicode flats/sharps. Tooltip shows full 'D# major' / 'D# minor'. - DetailPanel: same short format for consistency. Auto-fetch analysis: - App.tsx fetchClips() now fetches analysis for any ready clips missing BPM/key - Runs in background after clips load, updates state silently - No more needing to click into detail panel to see colors
