/* ============================================================================
   DEVELOPMENT — research, materials, crafting, and things that wear out
   ----------------------------------------------------------------------------
   The Armory sells permanent percentages. Once bought they are simply true
   forever, which is why the store stops mattering: nothing you own is ever at
   stake. Development is the opposite half of the economy.

     MATERIALS   salvaged from matches — spent, not banked forever
       RESEARCH    a tree that unlocks WHAT you may build, never a stat by itself
     MODULES     crafted, equipped, and visible on the machine that carries them
     WEAR        a module is consumed by use and eventually BREAKS

   Wear is the whole point. A module that lasts forever is just another store
   entry with extra steps; one that lasts eleven matches makes you decide when
   to spend it. And because every equipped module puts a mark on the Commander
   and the HQ in the field, its loss is something you SEE — the icon goes out,
   the bonus goes with it, and you know exactly what changed.
