availability starts
The date/time from which the product becomes buyable — a release date or the start of an availability window (free-text datetime literal; genuinely non-categorical). Cardinality one. Distinct from a sale price's price_valid_from (which scopes when a PRICE holds, a qualifier of the sale_price host): this scopes when the PRODUCT/offer is available at all. The realised datetime is downstream (L1); the fact that an offer is time-scoped is the grammar. A countdown to release is presentation over this value (A10).
Availability starts is free text, written for one product alone and never shared as a category.
It belongs to availability — whether it can be obtained.
