/* Clerq — clerq.nz marketing site.
   ---------------------------------------------------------------------------
   Deliberately separate from webapp/frontend/src/styles.css. The portal's
   design language is "ledger, not lifestyle-app" — tight radii, borders doing
   the elevation, dense type — which is right for a screen an adviser works in
   all day and wrong for a page whose whole job is to explain and persuade.

   What IS shared is the identity: the same brand teal (#12A6A6), the same cool
   slate ink (#14262D), the same mark. Somebody arriving at app.clerq.nz after
   reading this page should recognise it as the same product.

   Type is Geist Variable throughout, self-hosted. No CDN, no Google Fonts
   request: a marketing page for a privacy product should not leak its visitors
   to a third party on first paint. */
