// Wowee Open Spell Visual Kit catalog (.wsvk) — novel
// replacement for Blizzard's SpellVisualKit.dbc +
// SpellVisualEffectName.dbc + the AzerothCore-style spell
// visual SQL data. The 47th open format added to the editor.
//
// Defines per-spell visual presentations: cast-bar effect
// model, projectile model + travel speed + arc gravity,
// impact effect model, hand effect on the caster, and the
// animations + sounds that fire at cast / channel / impact
// time. Spells reference a visualKitId here from Spell.dbc
// (or WSPL.spellId.visualKitId), so this catalog binds the
// "what happens visually" to the "what mechanically happens"
// in the spell catalog.
//
// Cross-references with previously-added formats:
//   WSVK.entry.castAnimId    → WANI.entry.animationId
//   WSVK.entry.impactAnimId  → WANI.entry.animationId
//   WSVK.entry.precastAnimId → WANI.entry.animationId
//   WSVK.entry.castSoundId   → WSND.entry.soundId
//   WSVK.entry.impactSoundId → WSND.entry.soundId
//
// Binary layout (little-endian):
//   magic[4]            = "WSVK"
//   version (uint32)    = current 1
//   nameLen + name (catalog label)
//   entryCount (uint32)
//   entries (each):
//     visualKitId (uint32)
//     nameLen + name
//     descLen + description
//     castModelLen + castEffectModelPath
//     projModelLen + projectileModelPath
//     impactModelLen + impactEffectModelPath
//     handModelLen + handEffectModelPath

//     impactAnimId (uint32)
//     castSoundId (uint32)
//     impactSoundId (uint32)
//     projectileSpeed (float)         — units/sec, 0=instant
//     projectileGravity (float)       — 0=straight line
//     castDurationMs (uint32)
//     impactRadius (float)            — splash AoE in units
