Ethereal Dreamscape: Stairway to a Pastel Horizon

9:16 vertical pastel dreamcore surreal landscape. Pearl white thick staircase with a pastel sky blue closed door near the top, no railings or supports, rises from a perfectly calm mirror like shallow water surface, curving upward into enormous soft pink clouds. No land, buildings, or horizon only infinite reflective water below and endless pastel sky above. Water mirrors sky perfectly, erasing the boundary. Large soft clouds in blush pink, pale rose, peach, lavender, and pearl white float at varying heights, some engulfing upper steps. Pastel sunset palette: powder blue, periwinkle, pale lavender, baby pink, blush rose, soft peach, luminous pearl. Warm diffused light glows behind clouds, casting pink highlights on steps and soft reflections. Mood: peaceful, mysterious, nostalgic, dreamlike, whimsical, comforting. Style: dreamy airbrushed realism, ethereal surrealism, soft bloom, volumetric clouds, luminous atmospheric haze, dreamlike reflections, heavenly ambient lighting. Centered perspective, staircase lower middle foreground ascending into clouds, strong vertical depth. No people, text, religious symbols, gates, angels, castles, stars, neon, cartoon, anime, or obvious CGI.
