The editor below talks to POST /api/llm on this origin (the library's backend-proxy provider).
Paste an access token — an ai-gateway key (ak_…) — to enable grammar correction and ghost-text
completion. The token stays in this browser's localStorage and is sent only as the
Authorization header of /api/llm calls.
Select text or place the caret and use the toolbar's grammar action (or Ctrl+Shift+G);
ghost-text suggestions appear after a pause — Tab accepts, Esc dismisses.
