- NumberWords helper: decimal → "about seventeen pounds", DateTime → "3 days ago"
- PhotoAnalysisView: after analysis shows a card preview with large verbal price,
photo dots, "Looks good ✓" to save instantly, "Change something ▼" to reveal
a price slider (snaps to 50p, updates verbally as you drag) and title bar
- Card preview updates when live eBay price lookup completes
- SavedListingsView cards: verbal price as primary, £x.xx small beneath,
relative date ("yesterday", "3 days ago") instead of raw timestamp
- Detail panel also shows relative date
