 **Notes:** Implemented comprehensive breakpoint system using CSS custom properties. Established 6 mobile-first breakpoints (xs: 320px, sm: 640px, md: 768px, lg: 1024px, xl: 1280px, 2xl: 1536px) in variables.css. Created breakpoint mixin system with custom property utilities (--mq-sm, --mq-md, etc.) and implemented all utility classes using var(--breakpoint-sm) in media queries across utilities.css. Added container max-widths and responsive padding variables for each breakpoint. Modernized all existing responsive utilities to use the new system, including grid, display, text alignment, and dimension utilities.

+**Notes:** Implemented comprehensive fluid typography system using clamp() for responsive font scaling. Added fluid heading scale utilities (.text-fluid-xs through .text-fluid-3xl) that automatically scale from minimum to maximum sizes based on viewport width. Created breakpoint-specific font size adjustments for all breakpoints (.sm\:text-xs, .md\:text-lg, etc.). Added responsive line height utilities (.sm\:leading-tight, etc.) and complete font weight scale (.font-thin through .font-black). All typography utilities use the established CSS custom properties from variables.css for consistency and maintainability.
