//
// Per the cross-arch design (§2.4): each arch owns its own Relocation_Type
// and Relocation struct. The 65816's relocation kinds reflect the four
// address widths it can patch:
//
//   ABS16   2-byte LE absolute, low 16 of (base + target + addend)
//   ABS24   3-byte LE absolute, low 24 of (base + target + addend)
//   REL8    signed 8-bit PC-relative (target - (offset + 1))
//   REL16   signed 16-bit PC-relative (target - (offset + 2)) -- BRL, PER
