 - Target: Forge 1.18.2-40.2.4
 - Java version: **Java 17**
 - Output jar: `firefrostrules-1.0.5-1.18.2-forge.jar`

-## Key Differences 1.18.2 vs 1.20.1
-
-- `build.gradle` — change `minecraft_version` to `1.18.2`, `forge_version` to `40.2.4`
-- `mods.toml` — update `loaderVersion` range to `[40,)` and `[[dependencies.serverrules]]` MC version to `[1.18.2,1.19)`
-- MappingsChannel: use `official` mappings (same as 1.20.1 should be fine)
-- No breaking API changes between 1.18.2 and 1.20.1 for what this mod does
-- Config type: use `ModConfig.Type.SERVER` (not COMMON) — confirmed working pattern for 1.18.2 Forge, config goes in `world/serverconfig/`
