Imports: values (has, validate, the Holo*Error classes, the pure helpers) from @holostep-configurators/runtime-client, types from @holostep-configurators/runtime-client/contract, /math and /testing names from those entries; boot from the runtime module the root's loadRuntimeAtFloor resolves to. A type your page defines is your app's: declare it there, never import it from the package.

import type { PoseInput, Query, Session } from '@holostep-configurators/runtime-client/contract';
declare const session: Session;
declare const signal: AbortSignal;
declare const oakUrl: string;
declare const previewPose: PoseInput;                               // a look-only preview placement
declare const twoPrimitiveBodies: readonly Query[];                 // the 2F bodies by part id (C.8)
await session.find([{ name: 'mp-l*' }, { name: 'mp-r*' }]).set({ visible: false });   // the find() block: apply() never removes it
await session.apply({                                                                 // replaces only apply()'s own block

    { query: [{ name: 'Corpus*', kind: 'mesh' }, ...twoPrimitiveBodies],                 // the room finish
      set: { material: { ref: 'oak' } } },
    { query: { node: 'cab:42', name: 'Front*' },                                          // an override: later in order
