/* ============================================================================
   ENDGAME — why you play match fifty
   ----------------------------------------------------------------------------
   The career runs out at Warmaster and the store runs out at the Orbital Lance,
   which lands somewhere around match ten. After that the game had nothing left
   to ask of the player except percentages. Four systems replace that, and each
   one answers a different question:

     THREAT LEVEL   "is there anything harder?"    a permanent ladder
     OPERATIONS     "can I choose my own fight?"   priced, stackable modifiers
     THE WEEKLY     "how do I compare?"            one fixed contract per week
     MASTERY        "what have I not done yet?"    the long tail, visible

   The design rule shared by all four: difficulty the player CHOOSES must always
   pay, and the game must never hand out difficulty they did not choose. That is
   the difference between a challenge and a punishment.
   ============================================================================ */

/* ---- THREAT LEVEL ----------------------------------------------------------
   A ladder that ratchets. Beating the current level unlocks the next and banks
   it forever, so progress is never lost to a bad run — a loss costs the attempt
   and nothing else. Rewards climb faster than the difficulty does at the low
   end and slower at the top, which makes the early rungs feel generous and the
   last ones feel earned. */
