/* 
  -- DESIGN REFRESH --
  - Updated color palette for a slightly more modern and vibrant feel.
  - Reduced main border-radius for a sharper, cleaner look.
  - Enhanced box-shadows for better depth.
  - Added subtle transitions and hover effects for improved user experience.
  - Refined input focus states for better accessibility and visual feedback.
