   DIRECTION
   ---------
   Luminage sells clinical results, so money is treated like lab data:
   tabular figures that align on the decimal, original prices struck with a
   real drawn hairline rather than a browser strikethrough, and a mono
   utility face for references, labels and units. That precision is the
   signature; everything around it stays quiet.
