Quick Task 18: Multi-Column Metadata Display in Playlist Details — Summary

Replaced single-row <track-info> component rendering with a 5-column CSS grid layout (#, Title, Artist, Album, Duration) including a column header row, matching track-list's visual style.

Changes Made

Task 1: Replace track-info rendering with multi-column grid layout

Commit: ce23177

• Removed <track-info> component import (no longer used)
• Added formatMilliseconds import from @utils/time for duration formatting
• Added .track-header row with column labels: #, Title, Artist, Album, Duration
• Replaced <track-info> element with inline <span> grid cells showing track metadata
• Added 1-indexed playlist order number in # column (trackIndex + 1)
• Phantom tracks span the full grid width via grid-column: 1 / -1
• Added CSS grid styles: grid-template-columns: 40px 1fr 1fr 1fr 80px
• Column-specific styles: center-aligned #, right-aligned duration, tabular-nums, text truncation with ellipsis
• Removed stale .track-item:last-child { border-bottom: none } rule
• Updated .track-item padding from 6px 0 to 6px 8px for grid alignment

Deviations from Plan

None — plan executed exactly as written.

Verification

• cd frontend && npx tsc --noEmit — passed (0 errors)
• Pre-commit hook frontend-typecheck — passed
• All existing interactions preserved (click, dblclick, contextmenu, drag events unchanged)
• Phantom track rendering still uses warning icon / path / action button layout, spanning full grid width
