Sleep Cloud Zero-Gravity Bed Poster

A clean, high-end Japanese advertising poster for a luxury bed or mattress concept titled {product_title}, with the English subtitle {english_subtitle}, designed around the concept of zero gravity sleep. Use a minimal soft-white background with a pale powder-blue accent palette, airy negative space, and a calm premium wellness aesthetic. The layout is a single elegant poster composition: on the left, large Japanese headline typography in refined serif style, colored dusty pastel blue, with a small line of Japanese copy above it reading 「重力ゼロの、やさしい眠り。」 and the main title 「雲の上の眠り」 followed by the English subtitle centered below, flanked by thin horizontal lines. Beneath that, add two short blocks of Japanese body copy in smaller blue text describing a floating, liberating, comfortable sleep experience. On the right, feature a softly lit 3D-rendered bedroom vignette on a floating rectangular platform: 1 modern white bed with a low headboard, 2 white pillows, white bedding, and 1 light blue throw draped diagonally across the lower half of the bed. Make the bed appear to levitate slightly above the platform with a subtle blue glow underneath to suggest zero gravity. Behind it, place 1 tall arched window opening with a blue interior showing soft white clouds and sky. Add 1 small round bedside table holding 1 tiny vase with delicate stems and 1 small object, plus 1 round cream rug under the bed area, 1 light blue floor cushion, and 2 fluffy cloud props on the platform near the bed. Include additional faint clouds drifting around the poster edges. Along the lower left-to-center area, place exactly 3 circular feature icons with captions beneath them: 1 cloud icon for weightless floating comfort, 1 wavy-line icon for soft enveloping comfort, and 1 leaf icon for safe comfortable materials. At the bottom left, add 1 large rounded blue call-to-action button with white Japanese text {button_text} and a right-facing chevron, plus 1 outlined circular badge beside it reading 「期間限定」. At the lower right, add exactly 3 compact info lines with small icons: 1 delivery truck with 「送料無料」, 1 shield with 「安心の30日間返品保証」, and 1 calendar with the date {deadline_date}. Place a faint white {brand_watermark} watermark in the top-right corner. Overall style: soft 3D product visualization, Scandinavian-inspired minimalism, dreamy cloud theme, luxury bedding advertisement, diffused lighting, pastel blue shadows, pristine composition, polished commercial poster design.
