/* espresso-panel page layer - etelej.com lab-sites (scim).
   Page chrome on the espresso-panel tokens from espresso-panel-theme.css.
   Unlayered on purpose: it wins over the layered foundation without
   !important. Mirrors the lab-site page-CSS pattern (graphite-page.css):
   the same structural classes (.gt-masthead, .gt-console, .gt-btn, ...),
   espresso-panel looks. The identity contract: one amber hue on warm
   black, mono is the whole voice (UI, labels, numerals, prose), intensity
   is hierarchy, hairlines everywhere, 2px corners, state color encodes
   state only. */
