/* First Impact tokens.

   Two worlds, one set of semantic names (language.md §1, §7, §12):

     paper       khaki, what the shooter reads, writes and annotates
     instrument  dark, where measured or computed numbers are read

   The dark theme IS the instrument set applied globally — §12: "the light field
   variant IS the paper set … the dark instrument set is its twin. Semantics are
   identical in both." So the instrument values are declared once and bound three
   ways: by the dark theme, by the OS preference, and by .fl-instrument for a
   cluster sitting inside a paper page (§1: on desk screens the page never inverts).

   The --fl- prefix is public API. Do not rename it and do not add a second one. */
