Khalim Conn-Kowlessar 0bc9eac34c §5 slice 5: (68) appliances_monthly_w — Appendix L13/L14/L16a
E_A = 207.8 × (TFA × N)^0.4714 (L13) chained through monthly factor
1 + 0.157 × cos(2π × (m - 1.78) / 12) (L14) then watts via × 1000 /
(24 × n_m) (L16a). Column A typical-gain form — 1.0× conversion. L16's
0.67× reduced form deferred (new-build DPER/TPER use).

Verified against Elmhurst U985-0001-000490 (68)m row to ≤5e-2 W
(display rounding from the (TFA × N)^0.4714 term).

domna-domain

Shared domain types — Property, Properties, BaselinePerformance, Plan, PlanPhase, Scenario, ScenarioPhase, ScenarioSnapshot, Recommendation, OptimisedPackage, EpcPropertyData, etc.

Boundary: types only. No persistence, no IO, no business logic. Other packages and services depend on domna-domain; this package depends on nothing internal.

Domain definitions live in ../../CONTEXT.md. New types added here must match the glossary terms.
