/* chiquitito-data.jsx — "Chiquitito" mock layer.
   AIRS on low-code (n8n). A teammate built a lead-intake automation in n8n —
   a web form comes in, an AI cleans it up and drafts outreach, the record lands
   in the CRM. To secure it they dropped in the OFFICIAL Prisma AIRS node, three
   times (Prompt Scan · Mask Data · Response Scan). No code, no SDK.

   ============================================================
   INTEGRATION SEAM (FLIPPED) — the action now lives in n8n, not the hub.
   The page is a read-only one-pager whose PRIMARY control is an "Open in n8n"
   button. Two optional overlay fields under window.LASTROSE_BACKENDS.chiquitito:
     · editorUrl  — THE STAR. The real n8n editor URL the button opens (new tab).
                    Login-gated by n8n itself; absent → button renders DISABLED
                    (never a fake URL), so the export stays self-contained.
     · webhookUrl — survives ONLY to fill the copy-able curl snippet. Public, no
                    secrets. Absent → the curl shows a clearly-placeholder host.
   chiqEditorUrl() / chiqWebhookUrl() read these at call-time; both default null.

   sendChiquitito(...) below is kept as a FROZEN seam for any backend that still
   wants a live POST shape, but the one-pager no longer calls it — there is no
   live POST from the hub. Return shape (unchanged) — one of three:
     { record: { name, company, maskedMessage, summary, suggestedOutreach, segment },
       airs: { promptVerdict, dlpDetected, maskApplied, responseVerdict, scanned } }
     { rejected: true, reason, airs: { promptVerdict: "block", category } }
     { withheld: true, reason, airs: { responseVerdict: "block", category } }
