 * Defines how a cubemap should be constructed from source materials.
 * This is a discriminated union type with four possible formats:
 *
 * 1. Path-based: Specify a base URL and optional format for cube face images
 * 2. Faces-based: Provide explicit URLs for each cube face
 * 3. Preset-based: Use a predefined cubemap from available presets
 * 4. Color-based: Use a single color for all faces
 *
 * Only one of `path`, `faces`, `preset`, or `color` should be provided.
 *
 * @example
 * // Path-based cubemap
 * const pathCubemap: CubemapDefinition = {
 *   path: {
 *     baseUrl: 'https://example.com/cubemap',
 *     format: 'png'
 *   }

 * // Color-based cubemap
 * const colorCubemap: CubemapDefinition = {
