// structlit_arrfield_test — struct array-field init + read (global let/def and
// local lit). Migrated from test/wcc/949_structlit_arrfield_run.c (#249). BUG B:
// reading a [4]u8 field of a module-global struct SEGFAULTed on wwstage; BUG A:
// a local struct-lit array field fell to the scalar tail and dropped every
// element but the first. Fix = cg_structlit_fill array arm + def_isstructdef
// LOAD widening (ADDQ $field_off). cstage build+run was T1; cs==ww .s byte-id
// rides T2 (test-lang-byteid). The def row has a [3]u8 pad ahead of encmap, so
// the read exercises a non-zero field offset (the base64 std_encoding shape).
