// A small e-commerce schema — the |entity| ER card and the crow's-foot cardinality
// operators [SPEC 8, 9]. An entity's label is its centred title; rows read left as
// "field" "type", or "key" "field" "type" for a keyed (3-column) table. Entities are
// pinned so the schema reads as a graph, not a grid; `-o<` is zero-or-many, `-+<`
// one-or-many, `-o+` zero-or-one — the ring / bar / crow composed on the target end.
// Category is left in the default palette; the rest wear a hue (ink stroke, wash fill).
