Using the four reference stills (empty crypt, early debris, thickening debris, hardened stone) as an exact sequence, animate a smooth continuous transformation from the first frame to the last over 10 seconds. Locked camera, no zoom, no push in, no pull back, no rotation, no tilt, no orbit, no handheld shake. Silent clip, no dialogue, no music. NOTHING NEW ENTERS THE FRAME beyond the described debris and stone. The outlines and tissue must stay consistent throughout: NO redrawing, NO morphing beyond the described transformation, NO new lines appearing, NO extra objects.
