Design an Instagram carousel cover for a high-end fashion brand. The theme is the launch of a limited capsule collection featuring earthy linen suits for men. The visual identity references Bottega Veneta's neutral minimalism, with the calm austerity of Kinfolk and the editorial direction of Celine Homme by Hedi Slimane. The background is a soft stone texture, off-white with subtle grain. Color palette: stone gray (#BFB8AF), off-white (#F9F6F0), muted sage (#A3A295), accents in brushed brass (#D6BA82). Typography: elegant serif for titles, in all caps; grotesque sans-serif for body copy, left-aligned, lowercase. Layout is minimal, with asymmetrical negative space and one centered image of a linen jacket folded neatly on a sculptural surface. Headline: 'ESSENTIAL IS ENOUGH'. Subtitle: 'Summer '25 capsule – now available'. Visual should feel calm, timeless, and tactile. Output size: 1080x1350px vertical.
