5.5.x -> 5.6.x YAML

This migration keeps YAML storage, but changes where several data files live.

Steps

1. Back up your existing plugin data.
2. Move custom-types.yml, rarities.yml, series.yml, and packs.yml into the plugin data folder.
3. Restart your server.

Verify After Restart

• Rarities load correctly
• Series appear in commands and menus
• Packs still resolve their configured cards
• Custom types still participate in drops
