119 flattened mat4 vec3 row

// PINS: a WIDE all-f64 container — one entity row carrying four flattened ECS
// components (Transform mat4x4 as 16 columns, Position/Rotation/Velocity vec3
// as 9) — declared, inserted twice, swept back, with the declaration and the
// insert literal both spanning MULTIPLE LINES.
//
// This is ecs_bench_suite's simple_insert row (rust-gamedev's workload, not
// ours) in the only spelling the column system has: pure SoA scalars, one
// column per lane. Compound column TYPES (a vec3/mat4x4-valued column) remain
// uninvented surface — 690_020 carries that residue. Until they exist, this is
// the spelling a game consumer writes, and the corpus's widest store before it
// was seven columns (690_111); a 25-column store, and a `new`/`insert` block
// broken across lines, had never been asked for.
