// BOOT RACE GUARD verification (contrarian polish item).
// Proves a click fired BEFORE the wing bank finishes loading is handled GRACEFULLY —
// queued, not dropped — and then SELECTS the pointed-at board the instant the bank is ready.
// Also proves a normal post-ready click still selects -> carousel-to-front + 4-wall clad +
// collapsed detail (no Slice-2 regression), and that the Slice-1 invariants survive.
//
// To make the pre-ready window deterministic, we DELAY the /api/showroom/products response
// ~2.5s via route interception, then dispatch a REAL DOM click on #showroom-canvas at
// t≈1000ms (well before buildWingWall runs). We assert it queued, capture the pre-ready
// screenshot, let the bank load, then assert the queued click ended in a real selection.
