One brand colour, used with intent. Everything else is hierarchy and breathing room.

Buttons

Four variants, ordered by reach: Primary for the main action on a view, Secondary as a peer, Ghost / Text Link for tertiary or in-flow links, and Emphasis for a single hero CTA on pages whose entire purpose is that one action.

Button · Primary

Use: primary call-to-action. One per view, on the most important action (Request, Submit, Get Started).

Button · Secondary

Use: alternative or supporting action. Sits next to a Primary button (e.g. "Get Started" + "Read more").

Button · Ghost / Text Link

Use: tertiary action or in-flow link. Card footers, dense lists, secondary navigation.

Button · Emphasis

Download Brand Kit (.zip)

Use: the single hero action on a page whose entire purpose is that action — Brand Kit download, Register Your Interest, Download the Deck. Never as a regular Primary button.

Use rule: one distinct Emphasis action per page. The same CTA can be repeated as an anchor at the top and a closer at the bottom of a long page (the Brand Kit page does this), but never two different Emphasis buttons on one view.
