Design systems
The way a product moves and responds is the product, so we design it as a system.
A design system keeps everything coherent: type, colour, spacing, motion and behaviour, all pulling in the same direction. It is how a product feels like one considered thing rather than many parts.
We treat interaction as the substance, not the polish. How something responds when you touch it is what people remember, so we design those moments with care and reuse them everywhere.
