   Palette and type from intwasa-brand/identity-src.html. The rendering is
   deliberately spare and continuous: one ground from the top of the page to the
   bottom, no colour blocks, no boxes, no rules dividing sections. Hierarchy is
   carried by type scale and vertical rhythm alone; gold is reserved for the
   things you can click and for one hairline signature under each page's opening.
