// IMP-#84 u1 — FramePanel reject silent-automation contract.
//
// Stage 2 unit u1 scope:
//   1) `applyFrameSelection(candidate, onFrameSelect)` invokes onFrameSelect
//      with candidate.id verbatim for EVERY V4 label
//      (use_as_is / light_edit / restructure / reject) — no window.confirm
//      gate, no label-conditional branch, no frame swap.
//   2) Source-presence checks pin the FramePanel.tsx wiring so the runtime
//      button → handler → helper chain stays intact even though we cannot
//      mount React (no jsdom / RTL / happy-dom in Front devDependencies —
//      verified against the IMP-56 u20 `imp90_bottom_actions.test.ts` and
//      IMP-92 u5 `imp47b_human_review_toast.test.tsx` precedent that
//      explicitly skip DOM mounting).
//   3) No `window.confirm` substring remains in FramePanel.tsx after u1.
//
// Out of scope (Stage 2 exit-report contract):
//   - Home.tsx:523-524 `toast.error(aiReviewMsg)` (#92 operational-only).
//   - FramePanel reject badge/tooltip read-only labels at L102/L147/L156
//     (no popup trigger; preserved as silent operator hint).
//   - Backend `zone.provisional` emission (handled by u2 template-only).
