/**
 * Top Deals canvas — client-side lookup helpers.
 *
 * The Top Deals card list is a per-user system canvas seeded server-side
 * (see apps/server/src/services/canvas/top-deals-canvas.ts). It is identified by
 * the same reserved marker: a `cardList` canvas titled `TOP_DEALS_CANVAS_TITLE`.
 * These helpers resolve it from whatever canvases are already loaded in the store
 * (canvasesById) — the base-agent default resolver reads it here rather than
 * issuing its own fetch.
