refactoring-ui

Apply UI design principles from Refactoring UI by Adam Wathan & Steve Schoger. Covers visual hierarchy (size, weight, color, spacing), layout systems (spacing scales, grids), typography (type scales, line-height, alignment), color (HSL palettes, shade systems, accessible contrast), depth (shadow elevation, overlap), images (text on images, user content, icons), and finishing touches (accent borders, empty states, fewer borders).
