/* PSYROB shared theme.
   One file, two copies: psyrob.com (assets/css/psyrob-theme.css) and explorer.psyrob.com
   (psyrob-node: node/web/psyrob-theme.css). Edit both together so the sites stay identical.
   Tokens first; then the pieces both sites draw the same way (base type, focus, icons,
   the cross-site strip, the footer, status badges, chart text). Site-specific layout stays
   in each site's own stylesheet. */
