   Connust — marketing site
   Hand-written CSS, no build step, no framework.

   Design brief: trust as instrument, not decoration. The trust-score ring is
   the recurring motif. One accent (teal) against a navy ink on a cool
   off-white ground; the accent is spent on actions and the ring, nowhere else.
