/* Brain of Reese — Sources page (knowledge base index view).
*
* Wires the real `GET /api/docs` endpoint (import phase): stat cards +
* full-width document table, or the designed empty state when nothing is
* indexed yet. Cells are built with DOM APIs (textContent) — never
* innerHTML with document-derived data (XSS-safe by construction).
*
* Phase 19: the page joins the shared header (assets/header.js) — the
* whoami gate below runs on the module's cached promise (one request per
* page, shared with the header toggling).
*
* Phase 34 task 02: the header's functional controls are module-owned
* (assets/header.js): the Sync sources state machine (#sync-btn's
* §7.4 lifecycle — the page only renders #sync-result +
* #sync-error-banner off the module's "bor:sync-status" event) and the
* New chat binding (on a non-chat page "new chat" means going to the
* chat, fresh — the module clears the phase-14 conversation key and
* navigates to "/").
*
* Phase 26: the table's path links open the document in the
* almost-fullscreen modal overlay (assets/document-modal.js) on the
* SAME page — no new tab, no navigation. The link keeps its
* /document.html href as the no-JS / context-menu escape hatch;
* left-clicks are intercepted (preventDefault) and routed to
* openDocumentModal. The module is loaded through the relative import
* below — the header.js single-evaluation design (no direct <script>
* tag; esbuild inlines it into the page bundle).

* states, the admin-only load re-attach) lives in the shared header
* module (assets/header.js) — so the SAME button markup on ANY page

* banner, driven by the module's "bor:sync-status" event (detail = the
* GET /api/sync/status object):
*
* running → clear the result line, hide the banner (a new run starts
* clean — the module emits the frame immediately on
* click/boot, no 2 s poll lag);
* success → the last-result counts in #sync-result (fmtSyncResult —
* "added" always shown, zero terms omitted) + the catalog
* re-fetches live (the KB just changed — never a stale
* table) + the banner hidden;
* failed → #sync-error-banner with the error text, result cleared;
* idle → hide the banner, clear the result (a run vanishing with
* a server restart, or the post-403 cleanup).
