// Wowee Open Player Spawn Profile catalog (.wpsp) —
// novel replacement for AzerothCore's playercreateinfo
// SQL table plus the per-class/race starting fields in
// CharStartOutfit.dbc. Defines the initial state for a
// newly created character: starting map / zone /
// position, bind point (Hearthstone destination),
// starting items, and starting spells.
//
// One entry per (class, race) combination — a Human
// Warrior spawns at Northshire Abbey with a Warrior's
// Hammer and Heroic Strike already learned, while an
// Orc Hunter spawns in Valley of Trials with a starter
// gun and Aimed Shot. Death Knights have their own
// preset spawning at lvl 55 in Acherus.
//
// Cross-references with previously-added formats:
//   WCHC: race / class fields use the same bit layout
//         as WCHC class / race IDs.
//   WMS:  mapId / bindMapId reference WMS map entries.
//   WIT:  startingItem*Id reference WIT item entries.
//   WSPL: startingSpell*Id reference WSPL spell entries.
//
// Binary layout (little-endian):
//   magic[4]            = "WPSP"
//   version (uint32)    = current 1
//   nameLen + name (catalog label)
//   entryCount (uint32)
//   entries (each):
//     profileId (uint32)
