Vertical time grid starting from today, showing 7 days forward (not Monday-Sunday).
- Days as columns, hours as rows
- Same overlap/column-packing as waterfall but per-day column
- Today highlighted
- "Now" indicator line
- Compact enough to fit on a single screen without scrolling (6:00-22:00 visible range, earlier/later hours collapsed)
- All-day events in a row above the time grid
- Mobile: show 3 days with horizontal swipe, or collapse to waterfall
