    You are on a simple FAQ page presented as a single centered card.

    - Initial state: all panels are collapsed (no content visible).
    - Affordances: each header row is clickable and shows the standard AntD expand/collapse chevron.
    - No other interactive elements are required for success; expanding the correct panel is sufficient.

    This task uses Mantine's Collapse component (single disclosure region) inside a settings panel.

    - Layout: settings_panel.
    - The panel includes typical form controls as distractors (text inputs, toggles, and a Save button), but none are required for success.
    - Target component: a Mantine Collapse region labeled "Advanced options".
      - The Collapse content is controlled by a small button labeled "Show advanced" located near the top-right of the panel section.
    - Initial state: the Collapse region is collapsed (Advanced options content not visible).
    - Success is achieved when the Collapse region is expanded and its content is visible.
