Detailed physics tables for the crafting skill. Loaded on-demand.
| Effect | Sync | Timing | Confirmation | Easing | Spring |
|---|---|---|---|---|---|
| Financial | Pessimistic | 800ms | Required | ease-out | 200/30 |
| Destructive | Pessimistic | 600ms | Required | ease-out | 200/30 |
| Soft Delete | Optimistic | 200ms | Toast+Undo | spring | 500/30 |
| Standard | Optimistic | 200ms | None | spring | 500/30 |
| Navigation | Immediate | 150ms | None | ease | — |
| Local State | Immediate | 100ms | None | spring | 700/35 |
Time needed for users to:
Faster = anxiety. Slower = sluggish. 800ms is calibrated.
Permanent deletion needs deliberation but less than money. Warning color + timing = sufficient gravity.
Research shows 200ms is perceived as "instant" while allowing visual feedback.
300ms: Feels laggy
No network latency to hide. Users expect immediate response. Any delay feels broken.
