// func_8018A808, func_8018A8B8, func_8018A970 (all banked, same TU) establish the byte-proven
// idioms reused here: struct-assignment for 16-byte Blk16 records (`dst[0]=src[0];` etc.),
// and `extern void func_8012AD44(s32 *a0, s16 a1);` cast-at-call. func_8018A8B8/func_8018A970
// also already declare (*(LBlk16 *)&D_801C6C44) / (*(LBlk16 *)&D_801C6C7C) as a *singular* Blk16_8018A8B8 elsewhere in
// this TU, and (*(LBlk16 *)&D_800A5E88) likewise — since my splice point (replacing the func_80183710
// INCLUDE_ASM stub) sits ABOVE those file-scope decls/typedef, I cannot reuse the
// Blk16_8018A8B8 name here (typedef not yet visible) without a forward-reference problem, and
// per §138 (reconcile direction) redeclaring those two symbols with an INCOMPATIBLE type at
// file scope risks a clash once banked. So every symbol here is declared block-scoped (function
// body) using a locally-named struct type — block-scope externs don't collide with another
// function's block-scope externs for the same symbol (§S38/D2).
