The same conservator gently peels the thin conservation tissue away from the old fresco, lowering the removed sheet with both hands. Reveal the warm restored pigments gradually; the delicate tissue flexes naturally without melting into the wall. Keep her face, hands, pale linen shirt, chapel and fresco design consistent. Slow subtle camera push toward her pleased expression, warm dust-filled light unchanged. End on the exact supplied final composition with the sheet lowered. Native quiet paper rustling and chapel room tone, no speech or music, no text or logos.",
