A 1080x1920 px TikTok-format still advertisement for a fictional home fitness brand called IronNest. Studio-shot cinematic composition: a matte black adjustable dumbbell set rests on a light grey foam mat, photographed at a dramatic low angle (camera roughly 15 cm off the floor, 35mm equivalent lens) so the dumbbells loom large and heroic. Hard dramatic key light from the upper left creates strong specular highlights on the machined chrome dials; subtle fill from right keeps the mat visible. In the top-left corner, the brand monogram IN appears in a clean geometric sans at 90pt, white. Below center, two text overlays: "Build Strength at Home" in bold condensed sans, white, and "Starting at $149" in lighter weight. A bottom-anchored bright orange CTA button reads "Shop IronNest" with a small right-arrow glyph. The color palette is near-monochrome grey and black with chrome silver and the orange CTA.
