SCENE LOCK: static tripod forest framing from identical position and composition, same 35mm lens feel, same forest landmarks and hatch alignment preserved throughout the sequence. STAGE: realistic staging timelapse with workers carrying furniture and decor down into the bunker manually, assembling staircase railings, installing warm interior lighting, adjusting wall panels, organizing supplies, and preparing the underground luxury shelter for final reveal. DETAILS: humans physically moving every object, realistic hatch opening mechanics, warm light gradually filling the bunker shaft, subtle forest movement from breeze, natural reflections on brushed steel, smooth cinematic pacing, believable underground luxury preparation workflow. NEGATIVE: no text, logos, watermarks, teleporting furniture, floating decor, impossible hatch movement, warped geometry, fantasy technology, abrupt transitions, unrealistic lighting behavior.
