Design this interface in the "Mid-Century Modern" direction (movement, historical): Functional geometry and visual language of the mid-20th century.
Visual and interaction traits to use: flat illustration, warm tones, shapes.
Main UX risk: Can feel too themed. Mitigate it: Balance nostalgia with current controls.
Keep it accessible to WCAG 2.2 AA: contrast, visible focus, keyboard operation, 24 px minimum targets, reflow at 320 CSS px and reduced motion.
Keep the content, hierarchy and behavior the same as a plain baseline so the two can be compared. Do not claim the style performs better; the choice should be validated with users.
