//META: purpose=A StructDecl with exactly one scalar field lowers to an IRStructType carrying exactly one `field(...)` child — sibling of the empty (zero-field is not tested) and the eight-field boundary cases.
//META: intent=boundary
//META: pipeline_stage=lower
//META: warning=Auto-generated. May drift from source. Do not edit by hand.

// Boundary: struct-field-count lower edge (one). The doc says
// "StructDecl -> IRStructType with IRStructField children". With a
// single field the struct still lowers — exactly one `field(...)`
// row.
