/* The Jetvitals homepage: one flight, ramp to shutdown.
   The scroll engine (sc/scrollcraft.css) is the mechanism; this file is the page. It themes the
   engine by its tokens and never restyles .sc-stage, .sc-copy or any [data-sc-*] selector.
   Status colours follow the flight deck and the app: amber caution, red warning, green normal.
   They are used for status only; the one accent is the Jetvitals blue. */
