Use a cool, ethereal palette of frosted blues, soft violets, and pearl whites over translucent glass panels with high blur (backdrop-filter: blur(20px)) and subtle neon glows. Accent buttons and icons with shifting iridescent gradients—from aqua to lavender—with polished metallic strokes. Apply a luminous animated gradient background of slow-moving pastel waves under glass. Headlines use a refined serif in pearl white with soft drop shadows; body text in off-white with slight contrast boost. Glass panels have 80% opacity, crisp white borders, and a 3D floating drop shadow. Dark Mode inverts glass to deep indigo with violet glows. Ensure every element feels weightless, premium, and serene.
