/**
 * \@formspec/config
 *
 * Constraint validation for FormSpec - restrict features based on target
 * environment capabilities.
 *
 * This package provides:
 * - Type definitions for constraint configuration
 * - YAML/TypeScript config file loading
 * - Core validation logic for FormSpec elements
 * - JSON Schema for .formspec.yml validation
 *
 * @example
 * ```ts
 * import { loadConfig, validateFormSpecElements } from '@formspec/config';
 * import { formspec, field } from '@formspec/dsl';
 *
 * // Load constraints from .formspec.yml
 * const { config } = await loadConfig();
 *
 * // Create a form
 * const form = formspec(
 *   field.text("name"),
 *   field.dynamicEnum("country", "countries"),
 * );
 *
 * // Validate against constraints
 * const result = validateFormSpecElements(form.elements, { constraints: config });
 *
 * if (!result.valid) {
 *   console.error('Validation failed:', result.issues);
 * }
 * ```
