/**
 * AstermindLicense - MUI-style synchronous license loading.
 *
 * This class provides a simple, synchronous API for loading licenses
 * that mirrors MUI's LicenseInfo pattern:
 *
 * ```typescript
 * // BEFORE React imports (like MUI)
 * import { AstermindLicense } from '@astermind/astermind-premium';
 * AstermindLicense.setLicenseKeys([token1, token2]);
 *
 * // THEN React imports
 * import React from 'react';
 * ```
 *
 * The synchronous approach:
 * - Parses tokens immediately (base64 decode)
 * - Checks expiry synchronously
 * - Extracts features into the unified registry
 * - Does NOT perform crypto signature validation at load time
 *
 * This matches MUI's philosophy: validate format/expiry at startup,
 * defer expensive crypto operations.

     * This is the primary API for MUI-style license loading.
     *
     * @param tokens - Array of JWT license tokens
