-- Registry of hand-ported map scripts.  Map-specific behavior lives HERE,
-- never in engine classes (Critical Engineering Rule #9).
--
-- Each module returns { talk = { [TEXT_CONST] = script }, onEnter = fn,
-- onBoulderMoved = fn } where a script is a list of { "command", args... }
-- rows executed by src/script/ScriptRunner.lua.  Every hand-ported script
-- cites the pokered source it was ported from.
--
-- The modules land in src/script/MapScripts.lua as the engine's base
-- contribution: attachBase keeps the historical merge (talk tables merge
-- per TEXT constant, other hooks are replaced by later files, so
-- different files can each add NPCs to the same map), and mod
-- contributions from the map_scripts registry compose on top of it.
