// Shared state across all three custom elements. Svelte stores have // .subscribe (Svelte runtime uses it) AND a manual subscribe is exposed // here so legacy agent.js can wire vanilla DOM to the same signal that // Svelte components react to. import { writable } from "svelte/store"; export const highlightedDocId = writable(null); // { doc_id: number } — Briefing populates as it encounters citations, // SourcesFooter renders the numbered list from this. export const citeIndex = writable({});
