   L.U.M.E.N. — 10 LAYOUT
   The instrument shell.

   ---------------------------------------------------------------------------
   MOBILE FIRST, DELIBERATELY INVERTED
   ---------------------------------------------------------------------------
   The main N.O.V.A. OS terminal is designed for a desk and re-racked downward
   for smaller screens. This instrument inverts that, because it is used
   outdoors, before dawn, one-handed, with cold fingers.

   Everything below is the small-screen layout. The desktop arrangement is
   derived from it in 13-lumen-responsive.css, not the other way round.
   ========================================================================== */

/* --------------------------------------------------------------------------
   HEADER

   Sticky rather than scrolling away. On the main terminal the header is a
   status strip you pass by; here it carries the search field and the route
   back to AG Nova, and losing it behind a scroll on a phone is a small but
   constant irritation.

   It stays a strip, not a navigation bar: this instrument has one screen.
