光の渦、変わった。

16:9 horizontal, editorial magazine-style banner ad for a YouTube thumbnail / SNS ad. The overall tone is bright and fresh: white to off-white background with pastel accent colors, generous negative space, natural sunlight feel, and a clean sophisticated atmosphere. Main subject: a confident woman in her late 30s, with a slightly fuller body type, styled in a crisp white linen blouse and tailored beige trousers, holding a fresh green botanical stem. Her expression is assured but relaxed, looking straight into the camera with a subtle half-smile. The setting is a bright, airy studio with large windows and soft natural light streaming in. Lighting: natural window light diffused with a reflector, creating soft shadows and a luminous skin texture — shot on a DSLR with a 50mm lens for a fashion editorial look. Layout: title text in top-left corner in large bold Japanese: 「光の渦、変わった。」 in black. Main headline in the center, bold and impactful, in black with a red underline: 「宣言。」 in giant bold font. The person is positioned slightly to the right, leaving the left two-thirds of the frame for text and negative space. Text must be highly readable: white text with a thin dark outline or strong contrast against the background. Final note: render the subject as a photorealistic photograph, no illustration or CGI. Only the specified Japanese text should appear; no URLs, logos, watermarks, or decorative English words. Avoid 100% certainty claims, underage models, or excessive skin.
