=== DONUT RENDER DISTANCE ===
Donut Render Distance v1.3
Per-player render/view distance via explicit permissions.

COMMANDS:
  /drd                       - Open your distance info (blue GUI)
  /drd admin                 - Admin panel with blue theme (drd.admin)
  /drd reload                - Reload config (drd.admin)
  /drd check <player>        - Check player distances (drd.admin)
  /drd set <view|render> <player> <#> - Set distance (drd.admin)
  /drd grant <view|render|group> <player> <value> - Grant permission or group (drd.admin)
  /drd revoke <view|render|group> <player> <value> - Revoke permission or group (drd.admin)

PERMISSIONS:
  drd.admin                              - Full admin access (default: op)
  drd.bpsas                              - Bypass TPS auto-scaling
  drd.view.distance.<#>                  - View/simulation distance
  drd.render.distance.<#>                - Render/visual distance
  drd.world.<world>.view.distance.<#>    - Per-world view distance
  drd.world.<world>.render.distance.<#>  - Per-world render distance
  drd.group.<name>                       - Use group preset from groups.yml

GROUPS (groups.yml):
  Define presets. Players get "drd.group.<name>" permission.
  Example:
    groups:
      vip:
        view-distance: 12
        render-distance: 24
        bypass-auto-scale: true

  Then: lp user <player> permission set drd.group.vip

TEBEX INTEGRATION:
  RECOMMENDED (1 command per product):
    lp user <username> permission set drd.group.vip

  Alternative (direct permissions):
    lp user <username> permission set drd.render.distance.32
    lp user <username> permission set drd.view.distance.12
