Use Lora for h0/h1, Poppins for h2–h4. All body text and UI uses the system font stack. Brand colors are additive — never replace semantic tokens like --primary.
All GSAP animations must check prefers-reduced-motion. Use power2.out for entrances, back.out(1.7) for modals. Never invent new easing values outside the motion token set.
Never edit shadcn/ui source files. Customise via CSS variable overrides, Tailwind utility composition, or wrapper components. Use Hugeicons as the default icon library.
