Fixed critical bug where outflow would decrease when crossing from
building to capacity zone. The original formula caused a discontinuity.
**Problem:**
Old formula had outflow jumping from (inflow × ratio) in building zone
to (inflow - max) in capacity zone, causing outflow to DROP when
crossing the threshold.
Example (min=100, max=300):
- At inflow=300: outflow = 300 (100% sharing)
- At inflow=301: outflow = 1 (sudden drop!)
**Solution:**
1. Changed capacity threshold from max to 1.5 × max
2. Building zone now uses linear interpolation from 0 to 0.5 × max
3. Capacity zone retains max and shares all excess
New formula guarantees:
✓ Monotonically increasing outflow as inflow increases
✓ Continuous at all zone boundaries
✓ At inflow = min → outflow = 0
✓ At inflow = 1.5 × max → outflow = 0.5 × max
✓ At inflow > 1.5 × max → retain max, share excess
Zones:
- Deficit (inflow < min): outflow = 0
- Building (min ≤ inflow < 1.5×max): progressive linear growth
- Capacity (inflow ≥ 1.5×max): outflow = inflow - max
Changes:
- lib/flow-v2/engine-v2.ts: Updated getFlowZone() and calculateOutflow()
