- get_symbol: URL was missing '/raw' suffix + tried .json() on binary SVG → now returns download URL + curl command (like download_capture_file) - upload_symbol: URL was missing '/raw' suffix → now accepts SVG content string and POSTs to correct path - delete_symbol: returns 204 No Content, .json() would fail → removed .json() call (just returns message)
