--- ox_lib compatibility wrapper for zone creation and management.
--- Provides a small API around lib.zones (box, sphere, poly) to create/destroy
--- and lookup zones with automatic id generation and resource ownership.
---
--- Example:
--- local id = cZones.Create("box", { coords = vec3(0,0,0), size = vec3(2,2,2), onEnter = function(z) ... end })
--- cZones.Destroy(id)
---
---@module cZones
---@class ZoneData
---@field id string Unique id for the zone (generated)
---@field invoking string Resource that created the zone
---@field coords vector3? Center coordinates (box/sphere)
---@field points vector2[]? Array of points for poly zones
---@field radius number? Radius for sphere zones
---@field size table? Size table or vec3 for box zones
---@field zone any Internal zone handle returned by lib.zones
---@field debug boolean? Debug flag passed to lib.zones
---@field onEnter fun(data:ZoneData)? Callback invoked on enter (receives ZoneData)
---@field onExit fun(data:ZoneData)? Callback invoked on exit (receives ZoneData)
---@alias ZoneType "box"|"sphere"|"poly"

---@diagnostic disable: duplicate-set-field
