post/hosting/design-library/design

A complete, coherent design choice from a brief alone (every field optional): palette, type pairing, spacing and shape, sections, flow, closest template, and for apps shell, screens and component style; plus alternatives with a reason each. A brand kit (colours, fonts, voice) acts as constraints: the palette is built from the brand colours with every contrast correction reported, brand fonts without a web licence are replaced by the nearest open pairing. Deterministic and versioned (selectionVersion).
