Minimalist Off-White Custom Home Design Proposal Cover

Full prompt

An elegant, minimalist custom interior design proposal cover in a 16:9 aspect ratio, set against a flat, solid off-white background free of texture. The right 40% features an arched-frame architectural photograph showcasing a bright, sophisticated interior with light-toned flooring, sheer curtains, a sleek cylindrical pedestal, and a ceramic vase, bathed in soft daylight casting linear shadows. The left 60% contains a refined typographic layout: a subtle header in the upper left reads 'D.DESIGN', followed by a prominent, elegant main title reading 'Refined Space · Intelligent Living' in dark gray, an explanatory subtitle 'Tailored Residential Interior Solutions', a speaker credit 'Presenter: Xiaoding Gao', and a date stamp '2026.08.20'. A delicate horizontal rule spans the lower section with an accent block on the left and a small page number '01/10' at the bottom right. Clean editorial aesthetic, restrained warm neutral palette of cream and soft brown, generous negative space, and modern architectural elegance.
