=== FlashChat SSO (JWT) ===

1) Install the plugin (upload the zip in WordPress -> Plugins -> Add New -> Upload).
2) Go to Settings -> FlashChat SSO.
3) Configure:
   - Chat URL: your chat html page
   - Server Name: same serverName in FlashChat
   - API Key: your FlashChat api_key
   - Shared Secret: MUST match the secret you set in FlashChat Admin Panel -> Client Settings -> Website SSO Integration
4) Add the shortcode [flashchat] to any page.

Notes:
- The token is short-lived (default 5 minutes).
- The token is passed in the iframe URL as sso_token. Your chat UI must exchange it via /api/v1/sso/exchange.
