BentoGrid class

A scrollable bento grid that positions tiles of varying sizes using the skyline bin-packing algorithm.

Tile widths are expressed as fractions of the available width — no column count or fixed pixel widths needed. The grid always fills its parent.

BentoGrid(
  unitHeight: 180,
  items: [
    BentoItem(size: BentoItemSize.fullTower, child: HeroTile()),
    BentoItem(size: BentoItemSize.halfCard,  child: LinkTile()),
    BentoItem(size: BentoItemSize.halfCard,  child: LinkTile()),
    BentoItem(size: BentoItemSize.fullBar,   child: SectionTitle()),
  ],
)
