    The footer Engine Controls menu opens from a fixed mobile footer, so the mobile panel must not inherit desktop corner anchoring. Keep it viewport-fixed, full-width between token gutters, scrollable, and lifted above the executor footer plus mobile nav stack including safe-area, standalone, and ICB compensation.

    FNXC:EngineControls 2026-06-30-16:10:
    Browser verification showed the footer context can lose this low-specificity mobile override to later footer/card rules and collapse to the trigger's narrow corner. Keep a matching higher-specificity footer rule below so position:fixed and the full-width safe gutters win in the actual ExecutorStatusBar renderer.

    FNXC:EngineControls 2026-06-30-16:25:
    Tablet browser verification at 820px still overflowed with the desktop anchored popover. Extend the viewport-safe panel breakpoint through common narrow tablets so the footer trigger cannot place a 24rem menu outside the visible inline bounds.

    FNXC:EngineControls 2026-06-30-16:42:
    Browser verification at 1024px landscape showed the footer popover could still inherit the shared .card position and render off-screen. Keep the viewport-safe footer override active through that tablet width, and keep a footer-specific desktop rule outside the media query so .card cannot reset the anchored popover on wider screens.
