   Memrith — independent study.

   One stylesheet for the whole site. The previous site inlined a <style> block
   per page because each landing page was its own funnel with its own layout;
   a study is one document, so it gets one design system.

   Palette and type are carried over from the old site (Fraunces / Hanken
   Grotesk, self-hosted — no third-party font request, which matters on a site
   whose subject is privacy).
