pollDelayMs

double donner::editor::HandoffTimings::pollDelayMs = 0.0

Total time from worker render completion until the UI thread accepted the result.

wakeToPollMs

double donner::editor::HandoffTimings::wakeToPollMs = 0.0

Portion spent waiting for the UI thread's next frame once the result was pollable.

A result becomes pollable at render completion on every platform, so this equals pollDelayMs. It stays a separate field because it is the one with a meaning: "the UI thread had not run a frame yet". The browser used to insert a task-boundary hop between completion and pollability, and the split existed to tell that hop apart from this wait; The single-canvas replacement removed the hop along with the worker-surface presentation boundary.
