// Scroll-effect application. The host calls this script after
// the scroll-effect script has produced a status code and
// status argument. The script dispatches to the matching
// fine-grained natives so the host's `handle_read` itself
// carries no per-status switch. Each native applies the
// matching world mutation and emits the matching message.
//
// Status codes (matched against the item-effect status table
// in the manual). Codes 8, 9, 10 are placeholders; the
// `scroll_placeholder` native emits a generic message until
// the host gains real handlers for Sleep, Confusion, and
// Remove Curse.
//
// Inputs.
//   code     1 magic mapping, 2 teleport, 3 identify potions,
//            4 enchant weapon, 5 enchant armor, 6 light,
//            7 detect monsters, 8 sleep, 9 confusion,
//            10 remove curse.
//   arg      Per-code argument. Currently used by 4 and 5
//            (enchantment delta).
