 * Mainframe's accent (Petrol #0e6b7a, branding) for the server pages that use the Stack Overflow "Stacks" CSS
 * library (login, code, code app setup, one-time links, file preview). Its "secondary" scale (buttons, links, the
 * page background) is made from these three base values: 400 is the base, 100–300 lighter, 500 and 600 darker.
 * Loaded after stacks.min.css; a plain file, so the CSP stays without inline styles.
