The grid is the brand asset, not just the cont

Create a premium full-frame 2x2 social-story campaign poster for an original natural history brand named "PRIMORDIA ATLAS". The entire image must be completely filled by four vertical mobile-story panels arranged as a seamless 2x2 grid with no outer margin, no poster border, no empty background around the cards, and no floating mockup spacing. Each panel must touch the grid structure tightly so the four-card arrangement itself becomes the main visual symbol. The final image should feel like a Cannes-level museum campaign system: cinematic, intelligent, immersive, minimal, collectible, and instantly recognizable.

Style lock:
High-end cultural campaign design, ultra-realistic prehistoric photography, dark editorial museum branding, premium social-story layout, elegant UI framing, cinematic realism, restrained typography, strong system-based composition.

Core composition:
Fill the entire frame with four equal vertical story panels in a strict 2x2 grid, edge-to-edge, with only ultra-thin internal gutters between panels. No outer border, no surrounding gray space, no mockup background, no visible tabletop, no presentation margin. The top-left panel shows an extreme close-up portrait of a prehistoric predator’s eye, scales, and facial mass emerging from shadow and mist. The top-right panel shows a raptor-like dinosaur head-and-neck portrait in foggy grassland atmosphere. The bottom-left panel shows a towering fossil skeleton photographed from a low angle in deep museum darkness. The bottom-right panel shows a fossil skull near the lower portion of the panel with dark negative space above for event-style information. All four panels must feel unified, equal in scale, equal in visual weight, and locked into one continuous campaign surface.

Orbit motion logic:
Design the four panels so the eye travels in one controlled clockwise loop: top-left eye portrait, top-right living head profile, bottom-right fossil skull, bottom-left towering skeleton, then back to the top-left. Use directional gaze, light falloff, bone angles, headline placement, fog gradients, and tonal contrast to create a continuous reading circuit across the four quadrants. The grid must feel alive with internal visual circulation, not like four disconnected cards.

Port super-symbol logic:
Turn the full-frame 2x2 grid itself into the brand’s super-symbol. The upper row represents living prehistoric presence, the lower row represents fossil memory and extinction trace. Together, the four panels must function as one ownable emblem of "life above, relic below," instantly legible even at thumbnail scale. The campaign should feel like a museum identity system, not just a set of separate posts.

Lighting:
Use physically coherent cinematic lighting across the whole grid while preserving panel-specific moods. Top-left: low-key side light revealing leathery scales and a wet reflective eye. Top-right: soft diffused dawn light with mist and cool edge separation on the dinosaur profile. Bottom-left: focused museum spotlight from upper-left creating dramatic bone volume and readable shadow depth. Bottom-right: minimal exhibition lighting with subtle highlight on the fossil skull and elegant dark negative space above. Ensure the four panels feel related through shared tonal discipline.

Materials and realism:
Render living dinosaurs with hyper-real skin texture, scale variation, natural pores, believable eye moisture, realistic cartilage structure, and subtle atmospheric diffusion. Render fossils with dry mineralized bone texture, porous erosion, fine cracks, matte chalky surfaces, age wear, and believable museum preservation detail. The panel surfaces should feel like premium digital story cards with crisp edges and subtle glass-screen realism, but integrated directly into the full-frame grid.

Color strategy:
Use a restrained museum palette: charcoal black, deep slate blue, fossil gray, misty taupe, muted olive, weathered bone ivory, and cool steel highlights. Keep saturation controlled. The upper living-creature row should feel slightly cooler and more atmospheric; the lower fossil row should feel slightly denser, darker, and more mineral.

Typography and layout:
Use original English text only. Keep one clean brand title integrated at the top center across the upper grid line, such as "PRIMORDIA ATLAS", and a small website or campaign identifier integrated subtly near the lower edge if needed. Inside each panel, use elegant editorial serif headlines and restrained sans serif support copy. Suggested original headline directions:
top-left: "Before Memory"
top-right: "When Giants Breathed"
bottom-left: "Bones Of An Empire"
bottom-right: "After Dark At The Vault"
All text must be original, globally marketable, and visually disciplined. Do not copy any existing museum name, slogan, or layout text.

Story UI details:
Each panel includes a subtle story-style top bar with tiny profile icon, short account label, progress line, and close icon. Keep the UI understated and consistent across all four panels so it supports realism without distracting from the imagery.

Spatial rules:
Equal panel size, equal height, equal width, equal visual weight, no exterior padding, no mockup border, no gallery backdrop, no extra props. The full image must read as one edge-to-edge four-panel campaign wall.

Quality target:
Hyper-detailed, high-resolution campaign finish, cinematic realism, premium layout discipline, crisp typography, unified tonal system, pristine edge control, strong grid readability, no muddy blacks, no dead empty space, no visual clutter.

Negative prompt:
copied museum name, copied slogan, copied campaign text, outer border, empty margin, floating mockup, background around cards, uneven panel size, inconsistent gutters, warped perspective, cheap social template look, low-detail dinosaur skin, plastic fossil texture, unreadable text, cluttered UI, muddy shadows, dead black blocks, oversaturated colors, random props, distorted anatomy, fake bones, low-resolution detail, weak grid cohesion
