  Tournament bracket struct from GameServer.

  This is a stub module for SDK type definitions. The actual struct
  is provided by GameServer at runtime.

  parallel brackets, each crowning its own champion.

  ## Fields

  - `id` - Bracket ID (UUIDv7 string)
  - `tournament_id` - Owning tournament (UUIDv7 string)
  - `index` - 0-based bracket number within the tournament
  - `size` - Slots in this bracket (power of two)
  - `inserted_at` - Creation timestamp
