-- Structured custom code: lua.local.d/{maps,selectors,regexps}/*.lua are loaded

-- The loader is two-phase: every file is read first, then entries are registered
-- in maps -> selectors -> regexps order so cross-kind dependencies (e.g. a
-- selector that captures rspamd_maps[name] or compiles an rspamd_regexp from a
-- map) work via lua_extras.deferred(factory).
