/* COMSAT // GCS — tactical ground-control skin.
 *
 * Design rules (deliberate, keep them):
 *  - No rounded corners anywhere. No decorative gradients. No shadows.
 *  - Monospace everything; labels uppercase + letterspaced, data as-is.
 *  - Three signal colors only: phosphor green (ok), amber (caution),
 *    red (warning). Everything else is olive-grey chrome.
 *  - Color always rides on a state attribute set by cockpit.js
 *    (data-state / data-ok / data-warn / data-hot / data-wan / .engaged),
 *    never on decoration.
