Create a premium square flagship poster for a luxury interior design brand called AUREM CASA, combining Orbit-style visual guidance with Transit-style editorial restraint. The image must feel ultra-clean, sculptural, architectural, and internationally premium, with a strong brand symbol at the center and a photoreal luxury interior revealed within it. No copied text, no watermark, no clutter. Core composition: Use a warm ivory-beige gallery-like background with generous negative space. At the center, place one large three-dimensional sculptural monogram form inspired by a rounded architectural letter portal, carved with smooth thickness and elegant curvature. This monogram acts as the dominant brand symbol and also as a framing device. Inside its opening, reveal a serene photoreal luxury bedroom-lounge interior at sunset, seen straight-on with precise architectural balance. The poster should read instantly as one memorable luxury design icon: sculptural letterform outside, warm interior world inside. Orbit direction: Introduce a subtle but clear visual guidance system that leads the eye into the interior. Use one restrained curved architectural guide line above or around the monogram, echoing the monogram’s geometry and gently directing attention inward. The inner room composition should also reinforce this motion: the terrace opening, bed alignment, rug direction, low table placement, and sunset focal point should all draw the gaze from the outer poster surface into the warm horizon beyond the glass. Motion must feel quiet, intelligent, and premium, never decorative. Transit restraint: Keep the layout extremely minimal. Reduce all text to the essential brand hierarchy only. Remove secondary labels, extra notation, and any crowded information. Preserve large breathing room around the central symbol. The final image should feel like an international flagship branding poster rather than a brochure. Interior scene: A calm luxury bedroom and lounge space opening onto a terrace at golden hour. On the left, a low-profile bed with elegant linen bedding and soft layered textiles. On the right, a refined lounge chair with sculptural softness. At center, a low table on a muted textured rug. Floor-to-ceiling sliding glass doors open to a terrace with trees and warm sunset light beyond. The interior must feel warm, expensive, deeply livable, and perfectly styled, with impeccable architectural proportion and realistic material harmony. Lighting: Golden sunset light enters from the far exterior horizon, glowing through the open glass doors and creating a luminous focal depth within the room. Add soft ambient interior fill so furniture, bedding, curtains, and floor remain readable and dimensional. The monogram itself should cast delicate studio-like shadows onto the poster background, enhancing the sculptural object quality. Contrast should be refined, with soft transitions, no dead black, and no muddy highlights. Material rendering: The central monogram should feel like matte plaster, smooth limestone composite, or micro-cement with subtle tactile grain and soft shadowing. The interior should feature natural oak or walnut floor, linen bedding, soft woven rug, matte curtains, boucle or brushed-fabric lounge seating, clear low-iron glass, and restrained metal accents. Everything must be photoreal, tactile, and quiet-luxury in tone. Typography and branding: Use only a minimal editorial branding system. At the top center, place a refined monogram logo and the brand name “AUREM CASA”. Beneath it, add one small line: “Interiors shaped by light”. At the bottom center, place a large elegant serif headline: “SERENE FORM”. Beneath it, one tiny supporting line: “Private interiors for quiet living”. Typography should be dark taupe or warm charcoal, widely spaced, balanced, and clearly secondary to the central symbol. Color system: Warm ivory, soft sand, pale stone, muted taupe, walnut brown, sunset amber, and restrained charcoal typography. Keep saturation low and luxurious. The sunset inside the interior should be the only luminous warm accent. Style: Cannes-level luxury interior campaign, flagship architectural branding poster, premium editorial minimalism, sculptural identity design fused with photoreal lifestyle interior visualization, calm, collectible, sophisticated, globally marketable. Image quality and physical constraints: Ultra-detailed, high-resolution, coherent room perspective, realistic sunset depth, sharp but soft-luxury finish, no warped furniture, no distorted monogram geometry, no fake CGI look, no dirty wall texture, no excessive props, no random text, no visual noise. Negative prompt: copied original wording, generic interior brochure, cheap real-estate ad, fake CGI interior, warped perspective, cluttered furniture, noisy decor, plastic materials, overexposed sunset, muddy shadows, dead black corners, unreadable typography, random icons, watermark, low-end branding, distorted monogram shape, messy poster surface
