这版南瓜楼梯，比例差没对齐

Print the whole image as a linocut relief poster with limited screenprint color layers: carved blocks pressed in rich black ink on warm bone paper, plus one flat dusty-red layer and one small acid-green accent. The linocut signature is contact pressure -- compact ink islands and mottled pull texture where block meets paper, never directional carved gouges -- and no gradients anywhere: every tone is flat ink or bare paper, with hand-cut, crisp edges and visible grain across the bone ground. A tall vertical 3:4 poster frame centers one clean pumpkin cut exactly in half, flat cut side facing the viewer, filling the upper three quarters of the frame on a plain field that stays bone paper all around. The cut face shows flat bone-white ribs running top to bottom and one large curved seed cavity sunk into the lower middle; a curled black stem with one small acid-green leaf twists at the top. Inside the cavity, a narrow spiral staircase of flat dusty-red steps hugs the inner wall, winding down and inward toward one tiny unlit door -- a plain black rectangle, smaller than a single step -- at the cavity floor; the extreme scale gap between the stairs and that door is the whole point of the picture. No face is carved into the pumpkin and no figure stands on the stairs. The bottom quarter of the frame stays one wide, completely empty band of bare bone paper -- the poster's intentional title space. No lettering, numbers, signage, or watermarks appear anywhere; the door carries no plate, number, or lamp, and the bone paper shows its pull texture to every edge.
