Pace-adjusted high calculations were embedded in dashboard-utils alongside chart, profile, and modal helpers. This moves the pure pace model and reusable HM time helpers into focused modules while keeping dashboard-utils re-export compatibility for older callers.
Constraint: Preserve existing pace wording, thresholds, and calculation output.
Rejected: Split all remaining dashboard-utils helpers at once | model/chart/modal helpers have wider call surfaces and should move in separate reversible passes.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Tested: TypeScript diagnostics for pace-utils, time-utils, dashboard-utils, and FutureForecastModal
Tested: npm run build
Not-tested: Bundle analyzer size comparison.
