Exact gross amount in integer SEK minor units.
One entry per product that sold today, largest quantity first.
Products with no commercial sale in the current day are absent rather than reported as zero: the breakdown answers "what has been sold today", and an empty day is an empty list next to a zero total.
Current configured local-day commercial sales reconstructed from finalized commercial facts.
grossTotalMinor and products are produced by one grouped read, so the headline total and the per-product breakdown can never disagree about what the day contains. Both are derived from immutable item snapshots of commercial finalizations only; fulfillment state, catalog edits, and session-local state do not participate.
