The adversarial review found the ModalRenderGuard lagged the old
PortfolioEditorActive() signal by one extra frame on CLOSE (a possible 1-frame
"opaque panels" flash). Latch the overlay's open flag (already available via
spec.p_open) — "drew this frame AND still open after Esc/Close/outside handling" —
instead of just "drew last frame", so the guard drops and the acrylic re-capture
fire on the same frame the overlay closes, matching the old inline behavior on
both edges.
