/*
  The landing page's look: Lagoon, deeper (Phase 14.5), the same palette as the
  popup (apps/extension/src/popup.html) and the web app (apps/web/src/styles/
  index.css). test:landing holds the brand teal and the coral equal to theirs.

  The system's own fonts, on purpose: a web font would be a request to another
  host (or a file to keep), and the popup and app use system-ui too.
