## Title

    Solve wide layouts with bounded pane composition, not unbounded scroll nesting

## Body

    FACT: The examined responsive work traced wide-layout defects to an unbounded parent scroll, a hard map minimum height, and separate header ownership. INFERENCE: Responsive quality depends on layout ownership and bounds, not only on CSS breakpoints. RECOMMENDATION: Use one shared header, bounded list and map panes, explicit compact or expanded thresholds, and state-retention tests through resize.
