Minimal Luxury Brand Concept Slide

Goal: Create a minimalist luxury brand concept presentation cover slide for {argument name="brand name" default="BRAND"}, using a split editorial layout with sparse typography and a cinematic architectural photo.

Canvas: 16:9 widescreen slide, clean white background on the left half and a full-height photographic image on the right half. Use a refined monochrome palette: white, charcoal, deep navy-black, cool gray, and soft daylight.

Layout: Divide the slide vertically at the center. The left 50% is a white design area with generous negative space; the right 50% is a photo panel. On the far left, place one thin vertical line near the margin, broken into two segments with the vertical word “BRAND” centered between them. Near the top-left area, set the large spaced-out headline “CONCEPT”. In the middle-left area, place a small abstract geometric logo made from exactly 2 dark navy square/rectangular blocks, followed by the large spaced-out title “KEY MESSAGE”. Under the logo/title row, add one short horizontal rule, then exactly 2 small supporting text lines: “Short statement line” and “Supporting statement line”.

Text content: Use {argument name="main headline" default="CONCEPT"} as the top headline, {argument name="key message text" default="KEY MESSAGE"} as the central title, and the two supporting lines {argument name="supporting copy" default="Short statement line / Supporting statement line"}. All typography should be uppercase or title-like where shown, with wide letter spacing, thin modern sans-serif font, dark navy-black color, and precise alignment.

Photo panel: The right half should show a quiet, high-end architectural interior with concrete walls, tall floor-to-ceiling windows, soft natural light, and strong diagonal shadows. Include exactly 1 human figure: {argument name="photo subject" default="a woman in a long black coat, seen in side profile, standing calmly and looking out the window"}. The figure should be positioned slightly right of center in the photo panel, elegant and contemplative, with a low bun hairstyle and minimal detail.

Visual style: Premium Japanese/Scandinavian editorial design, calm, spacious, museum-like, understated corporate branding, cinematic realism on the photo side, sharp typography on the white side.

Constraints: Keep the composition uncluttered. Use exactly 1 vertical brand label, exactly 1 headline, exactly 1 abstract logo, exactly 1 central title, exactly 1 horizontal rule, exactly 2 supporting text lines, and exactly 1 person in the photo. No extra icons, no mockup borders, no watermark.
