Description: Elements participate in several overlapping scopes: host ownership, layout behavior, focus state, event handling, and rendering policy. Passing every capability through every operation would make element authors and framework adapters carry plumbing that has nothing to do with their component logic. Nodes with inherited contexts provide ambient, subtree-scoped capabilities while still allowing a descendant to override any individual concern. The tree at this layer records semantic attachment, not visual order. That keeps the primitive small and allows the ordered host tree introduced later to define presentation without turning every middleware concern into a layout concern. import { Node, createContext } from './core.ts'; const root = new Node(); const child = new Node(root); const color = createContext('color'); color.set(root, 'cyan'); color.get(child); // => "cyan" This PR adds the minimal Node and Context classes, parent references, child collections, and prototype-inherited context storage inside the UI core. createContext() remains as the ergonomic context factory, with tests covering inheritance, overrides, local ownership, defaults, and null-terminated lookup.
