Major redesign of preset system from static templates to adaptive algorithms:
**Grid preset** (fully adaptive):
- Now arranges ALL windows in best-fit grid (2x2, 2x3, 3x3, etc.)
- Minimum: 2 windows (down from 4)
- Algorithm calculates optimal rows/cols for any N windows
- Examples:
* 4 windows → 2×2 grid
* 6 windows → 2×3 grid
* 9 windows → 3×3 grid
**Side-by-side preset** (adaptive with limit):
- Arranges 2-4 windows in single horizontal row
- Maximum 4 windows (prevents unusably narrow splits)
- Equal splits: 50%, 33%, 25%
- Clear error message if >4 windows
**Main + Sidebar preset** (unchanged):
- Already worked correctly (intentionally hierarchical)
- One main window (70%) + sidebars stacked (30%)
- Adapts naturally to any N ≥ 2 windows
Architecture changes:
- Replace static MosaicNode templates with generate() functions
- Add minSlots/maxSlots instead of single slots field
- Implement buildHorizontalRow(), buildVerticalStack(), buildGridLayout()
- Remove fillLayoutTemplate() (no longer needed)
- Remove extra window stacking (all windows now equal)
Benefits:
- No arbitrary hierarchy (no "featured" vs "extra" windows)
- Matches tiling window manager patterns (Amethyst, yabai, etc.)
- More intuitive: "grid" grids ALL windows, not just first 4
- Better UX: Works with any number of windows in range

Animation improvements:
- Use professional easing curve: cubic-bezier(0.25, 0.1, 0.25, 1)
- Reduce duration from 200ms to 150ms for snappier feel
- Enable animations only during preset application (not manual resize/drag)
- Add CSS layout containment for better performance
- Add/remove 'animating-layout' class to control when animations occur
UI consolidation:
- Merge layout preset dropdown and insertion settings into single control
- Create unified LayoutControls component with sections:
* Presets (apply existing layouts)
* Insert Mode (balanced/horizontal/vertical)
* Split ratio slider with +/- buttons
- Remove separate icons, now just one SlidersHorizontal button
- Cleaner, more discoverable interface
Benefits:
- Smoother, more natural-feeling animations
- No animation jank during manual operations
- Single unified control reduces UI clutter
- All layout settings in one place
