/**
 * corpus-save.js — Shared "Save to corpus" handler.
 *
 * Two trigger paths:
 *
 *   1. Tool pages — buttons with class="js-save-corpus":
 *      data-content-id="<id of element with text>"
 *      data-tool="<source_tool slug, e.g. korrespond>"
 *      data-suggested-title="<pre-filled title>"  (optional)
 *
 *   2. Dashboard chat — page code calls:
 *      dialog.dataset.pendingContent = "...";
 *      dialog.dataset.pendingTool    = "dashboard-chat";  (optional)
 *      dialog.showModal();
 *      Title and tags are populated by the caller before showModal().
 *
 * Endpoint resolution: if window.DBN_DASHBOARD is present (dashboard pages),
 * POST to /api/dashboard/save-from-tool.php; otherwise fall back to the
 * legacy /api/save-to-corpus.php so existing tools keep working.
