/* OpsNorth marketing site (feature 019).
   Visual system derived from cloudsafe.com — OpsNorth is a CloudSAFE product and the endorsement
   is the credibility. Dark-first, with light reserved for conversion moments only (cloudsafe.com
   uses exactly two white sections, both CTAs; so does this page).

   Self-hosted from the marketing bucket (FR-061). No external font host at all, which is why the
   FR-063 CSP can say `font-src 'self'` with no exception.
