Design and build an interactive portfolio website for a visual artist where the art takes center stage. Aim for a minimalist, artful look with smooth transitions, fast load times, and excellent behavior on mobile and desktop. Include two galleries: a public showcase and a client-proofs area behind login. Use Google Cloud Identity Platform for authentication. The main gallery should automatically pull high-resolution images and basic metadata from the artist’s Adobe Creative Cloud library so new work appears without manual uploads. Please implement it with SolidJS and prioritize performance and subtle motion.
