Build it around the business.
A pale gallery canvas, off-centre product or artwork composition, large disciplined sans-serif captions and a spare index; image zoom, material details and a considered enquiry pathway. Alternate full-bleed details with quiet reading areas.
Keep the purpose in view.
Do not default to beige cards, fake artwork, or hide price/scale/context if known.
On smaller screens, recompose the layout, prioritise the main action and retain readable type. Keep keyboard controls, visible focus and a reduced-motion alternative.
