Until 0.2.0 the shop kept its old slot count until the next roll (a refresh or the round start), so a
level-up 1→2 (险境: 3→4 operator slots) or 3→4 (4→5; 标准: 5→6) showed no new card.
PlayerState._openLevelSlots (player/economy.js): the extra slots of the new level are appended to the
chess slots (the item slot stays after them), each drawn at the new level; [ASSUMED] the new card follows
the freeze toggle as a manual refresh's cards do. audit.js checks the slot count and that every card
shown before stays in place. Docs: META.md §3 / §7, PLAYING.md.
Golden: matches — all 18 scenarios moved (solo-FUNNY-1/2, solo-NORMAL-1/2, solo-HARD-1/2, solo-ABYSS-1/2,
coop2-NORMAL-3, coop2-HARD-4, coop3-ABYSS-5, coop4-FUNNY-6, coop4-ABYSS-7, coop2-NORMAL-8-serverrun,
solo-HARD-9-boosted, coop2-ABYSS-10-boosted, coop2-NORMAL-14-standins, coop2-NORMAL-70-diy): every bot
levels its shop and now sees (and draws the shop RNG for) the new card at once, so purchases and boards
part from there. roster / bonds / fields / standins / diy unchanged; no engine error stored.
Tests: test/match/feedback5-shop-levelslots.test.js (new).
