Fires once per unannotated string field per generated row, which floods
the console under default WARN gate (e.g. CartItem.productName x N rows).
It's informational ("picked the generic faker.lorem fallback"), not an
anomaly, so it belongs at DEBUG. Wrapped data construction in a lazy
thunk so it pays zero cost when filtered.
