Views

The entire view system is built from a small number of composable elements: a node, a tile, a column, and a master-detail split. These four pieces nest recursively — a column of tiles where selecting a tile opens another column — so the same structure that displays a flat list also handles arbitrarily deep, mixed-orientation navigation without any additional wiring.

The view hierarchy wraps DOM elements rather than extending them. This is deliberate: the DOM API is large and mutable, and subclassing it tightly couples framework code to browser internals that change across engines and versions. Wrapping keeps the boundary clean — each layer in the class chain adds exactly one capability (visibility, event listening, gestures, layout, styling), so any layer can be understood, tested, or replaced independently.
