Defined in: [packages/core/src/domain/schemas/health/energy-balance.ts:28](https://github.com/pablo-albaladejo/kaiord/blob/3eacbe62ef72342d970523967cc5155b5935bb85/packages/core/src/domain/schemas/health/energy-balance.ts#L28)

Computed per-day energy-balance view-model — not a persisted payload but the
shape the SPA/chatbot read.

`intake_kcal` is nullable: `null` means the day is untracked (never a silent
zero). `net_kcal` is correspondingly nullable — without a tracked intake
there is no net (never a misleading zero or full-surplus). `target_kcal` is
nullable when no goal is active. Macro targets and actuals are optional
because they only exist once a goal / intake is present.
