/* Entropic Labs — The Observatory.
   ==========================================================================
   Same building, darker room. The palette, fonts and spacing conventions are
   the studio's, lifted from index.html so the two rooms match; what changes
   is the light level and the fact that everything is instrumentation rather
   than page furniture.

   One stylesheet serves phone and desktop. The Observatory is a canvas app
   whose layout is decided at runtime from viewport and pointer type, so it
   has no separate m/ build — the other pages are prose and can afford a
   hand-tuned twin, this cannot.
