Swiss-style editorial city poster built on a giant letter (templated)

Design a contemporary Swiss Style editorial poster for Moscow, Russia. Use a large bold sans-serif capital letter "M" as the main typographic structure. The "M" must be very clear, clean, geometric, solid, and dominant, with no stroke outline, no border, no shadow outline, and no decorative treatment. The silhouette of the letter must remain easy to read at first glance. Do not let the illustration obscure or distort the shape of the letter. The poster should follow a precise left-aligned Swiss grid system with generous negative space. Inside the "M", create a simple, logical, restrained flat illustration of the city's landscape character. Use only a few essential visual elements: simplified modern skyscrapers (Moscow City business district), the calm curve of the Moscow River, a subtle silhouette of the Kremlin walls and towers, onion domes of Saint Basil's Cathedral in simplified geometric form, a soft green park landscape (Gorky/Zaryadye Park), and two pedestrians on a clean riverside walkway. Keep the composition minimal and spacious. Do not add too many landmarks, people, signs, vehicles, monuments, statues, fountains, trains, or buses. The illustration should suggest the city's identity where imperial history, monumental scale, modern glass skyscrapers, riverfront public spaces, and urban rhythm coexist in a clean contemporary way. Use flat vector shapes, clean silhouettes, minimal linework, simplified architecture, and believable scale. The illustration should support the letter, not compete with it. Allow only extremely subtle overlap outside the letter frame using simple organic/atmospheric elements (a few riverside leaves or soft mist). Keep ~97% of the illustration inside the letter; it must remain clearly readable and dominant. Place the headline "Moscow" below the letter in bold sans-serif type, title case, left aligned to the same grid. Under the headline add a short body paragraph in small regular sans-serif text, left aligned, with refined editorial hierarchy: "Moscow moves through grand historic layers, monumental architecture, river bends, and a dense modern skyline. Between imperial heritage, Soviet scale, and contemporary urban energy, the city holds a character that is powerful, structured, and constantly evolving." No icons, no badges, no decorative symbols. Swiss minimalist feel: strong grid, precise alignment, asymmetrical balance, clean typography, generous negative space. Color palette: warm ivory background, deep navy or charcoal typography, concrete gray, glass blue, pine green, Kremlin-red accents, river blue-gray, pale beige, soft black. Matte paper finish, subtle paper grain, crisp edges, flat contemporary illustration, print-ready. Negative prompt: photorealistic, 3D render, glossy, maximalist, overcrowded city, complex illustration, too many details, too many landmarks.
