/**
 * Video Generation Error Codes
 *
 * Centralized error codes for video generation operations.
 * These are for runtime/execution errors during video generation.
 *
 * Pure option/shape validation (missing image option, invalid config values, etc.)
 * is handled by parameterValidation.ts using ERROR_CODES from errorHandling.ts.
 *
 * Error categorization:
 * - INVALID_INPUT → ErrorCategory.execution (runtime I/O failures)
 * - parameterValidation errors → ErrorCategory.validation (schema/option issues)
 *
 * @module constants/videoErrors
