/* Optronix footer, v4 format. A standalone copy of the main site's footer (css/ox/ox.css,
   section 17, on the redesign) for the one-page sub-sites, so all three Optronix sites end the
   same way. Everything is scoped to .ox-footer and carries its own tokens, so nothing here
   touches the page above it. The same file sits in workplacetech/css/ and energy/css/; change
