 * PATTERN FOR SCROLL CONTAINERS:
 *
 * .scroll-parent {

 *   flex-direction: column;
 *   min-height: 0;        ← Required: allows shrinking below content height

 *   min-height: 0;        ← Required: allows shrinking
 *   overflow-y: auto;     ← Enables scrolling
 * }
 *
 * .fixed-header-or-footer {
 *   flex-shrink: 0;       ← Prevents shrinking
 * }
 *
 * FOR CSS GRID:
 * - All grid children need min-height: 0
 * - Use 1fr for flexible rows/columns
 *
 * HIERARCHY IN THIS APP:
 * html/body (100%) → .shell (100vh) → .content (1fr) → columns → scroll areas
