pub const PHASES: [&str; 17];Expand description
The 17 conversion phases the worker times, in emission order — the index into a
TelemetryRecord::phase_us entry and the label of a per-phase P99 row. Kept in lock-step with
the latexml-oxide worker’s telemetry writer; a shorter/absent phase_us (the failure path)
simply contributes nothing to the tail phases.
