SUNSET ROADS 1.19.2 -> 1.21.1 CONFIG MIGRATION

This archive is based on the NEW 1.21.1 config and selectively carries over old settings where the same key/setting still exists, plus explicit AE2/JEI migrations. It intentionally does NOT overwrite renderer configs or loader configs.

NOT migrated automatically:
- Rubidium / Rubidium Extra / Magnesium Extras / TexTrue Rubidium Options
- Oculus
- Fastload (removed because it crashed world loading)
- old Dynamic Lights Reforged config (new Dynamic Lights uses different files)
- Create old worldgen sub-settings (Create 1.21.1 moved/changed these; do not copy blindly)
- old Default Options options.txt/keybindings.txt (Minecraft version + mod key IDs changed)

After installing this config, configure Minecraft options/keybinds in 1.21.1, then run /defaultoptions saveAll.
