 * The PackingGrid is a grid that shows the important items bigger without sacrificing the weight of the items.
 * Rows and columns are separated so that items are dynamically placed within the horizontal and vertical space rather than arranged in an orderly fashion.
 * If `sizeWeight` is higher than `ratioWeight`, the size of items is preserved as much as possible.
 * Conversely, if `ratioWeight` is higher than `sizeWeight`, the ratio of items is preserved as much as possible.
 * @ko PackingGrid는 아이템의 본래 크기에 따른 비중을 해치지 않으면서 중요한 카드는 더 크게 보여 주는 레이아웃이다.
 * 행과 열이 구분돼 아이템을 정돈되게 배치하는 대신 가로세로 일정 공간 내에서 동적으로 아이템을 배치한다.
 * `sizeWeight`가 `ratioWeight`보다 높으면 아이템들의 size가 최대한 보존이 된다.
 * 반대로 `ratioWeight`가 `sizeWeight`보다 높으면 아이템들의 비율이 최대한 보존이 된다.
