____________

[BRAND NAME].
Act as a graphic design creative director constructing a highly structured "Campaign Visual Identity Grid."

COMPOSITION (SPECIFIC 2-COLUMN ASYMMETRICAL LAYOUT):

The image must follow a strict 2-column grid structure, exactly like the layout seen in professional campaign boards.

LAYOUT STRUCTURE (TOP TO BOTTOM):
ROW 1: One single, full-width rectangular block (e.g., a wide photo).
ROW 2: Two equal-sized square blocks side-by-side.
ROW 3: One single, full-width rectangular block
ROW 4: Two equal-sized square blocks side-by-side.
ROW 5: One single, full-width rectangular block at the bottom.
The grid must be perfectly stable, with all blocks forming this exact pattern.

CRITICAL CONSTRAINTS:
FULL BLEED (100% COVERAGE): The grid must occupy the ENTIRE canvas area from edge to edge. There are absolutely NO margins, NO borders, and NO background space visible.

ZERO SPACING (NO GAPS): The grid tiles must be seamlessly abutted. There should be absolutely NO gutters, white lines, or spacing between the blocks. They must touch perfectly to form a solid wall.

GLOBAL RULES:
Typography: Use ONLY ONE font.
Uniqueness: Every photo cell must be UNIQUE. No duplicates.

THE GRID CONTENT & SPECIFIC TEXTURES (3 TYPES):
Distribute these three block types rhythmically throughout the specific 2-column layout defined above:

TYPE A: THE LOGO BLOCK (PRINT GRUNGE):
A solid block in the brand's primary color containing ONLY the official [BRAND NAME] logomark centered.
Texture: Distressed screen-print texture with slight ink bleed and grunge noise.

TYPE B: THE SLOGAN BLOCK (PRINT GRUNGE):

A solid block in a contrasting brand color containing ONLY the official [BRAND NAME] slogan.
Texture: Heavy distressed ink texture and grunge print effects on typography and fill.

TYPE C: CAMPAIGN PHOTOGRAPHY (HALFTONE):
High-contrast B&W action shots or portraits relevant to the brand.

Texture: Apply strong halftone dot patterns (raster dots) and heavy film grain. Use "Multiply" color blending to wash the photos in the brand's specific color palette (duotone effect).

The problem:

Nano Banana is messing up these:
- layout structure
- slogans (sometimes)
- grid content distribution

I've been tweaking the prompt back and forth - no result:
- you either get a good grid, but other details are failing
- or you're getting some grid weirdness

It clearly shows that AI tech is far from "replacing human"
Graphic designers are not cooked (at all).

AI won't work for "everything"
It's a great assistant for specific assets creation, quick iterations and tweaks

But complex, multi-layered workflows requires a human with skills
Even complex prompts & multi-model agents are suck compared to pros

I loved the visuals NBP spits out with this prompt tho
So, this is why I share it with you here
