/* Silent Ratchet: shared visual system for every page.

   Rules
   - Two typefaces with fixed jobs. Source Serif 4 is the voice: the wordmark, headlines, reading text.
     Schibsted Grotesk is the mechanism: actions, status, navigation, legal headings.
   - Black ground, warm white type. No accent colour; the call to action is the only solid light shape.
   - Wordmark: "Silent Ratchet", sentence case, serif semibold. Never letterspaced, never all caps.
   - Motion moves forward in clicks and never slides back. One place uses it: the call to action.
