Sollervir 3c3926e — Fixed a real bug: units on the y=228 row of the build grid (slots 13-16) were 104px from the enemy path, 1px beyond a level-2 unit's old 103px range, so any level-2 unit placed there (e.g. Special Forces) could never attack; base range was raised from 90 to 110px so every level reaches every slot, with a new regression test guarding it. Summon Boss failure penalty changed again: instead of stealing a field unit, a failed capture now locks re-summoning for 500 seconds (success still locks for 120s). Treasure chest jackpot odds are back to per-tier values (50/45/40%, was a uniform 10%) with costs unchanged (25/125/250 gold) and payout caps rebalanced per tier to hold the ~0.9x expected-value-to-cost ratio. 219/219 tests, clean release-check.
