property ◇ token a chosen word
size
The categorical size a product is offered in — a chosen, filterable universal facet, not a measured extent. One growing token vocabulary absorbs every kind's size scale (apparel S/M/L, footwear US-9/EU-42, ring 7, battery AA/AAA/D, mattress Queen/King, food Small/Large), L13. Distinct from the numeral physical dimensions (height/width/depth) — the product's measured extent in `measurement`; size here is a selected option, never derivable from a single measurement. Read alongside size_system, which names the scale the values are expressed in. Whether size is a buyable variation axis is the per-kind `axis` mark, not a fact of this property.
Size is answered with one word chosen from the sizes list — the same word shared across every product that uses it.
It belongs to facet — one facet of a product.
