A.4 cont.: card-deck icon placeholder mode (no-deck-equipped) styled like empty dice slot — TDD. User polish 2026-05-25 PM after browser-verifying the kit-bag dialog: when no deck is equipped (kit-bag-placeholder branch fires) the new card-stack icon should not animate + should render w. the same dimmed rgba(--quaUser, 0.x) palette as the existing fa-dice empty slot next to it, not the bright --terUser stroke / --priUser fill of an equipped-deck icon. Two SCSS changes: (1) Removed .deck-stack-icon:hover + .deck-stack-icon:active from the splay-trigger selector list — only wrapper-based selectors (.token.deck-variant, .kit-bag-deck) fire the fan-out now. Placeholder icons land inside .kit-bag-placeholder (or game_kit applet's .kit-item empty-state) which aren't in the trigger list, so they stay static no matter where the user hovers. (2) New .kit-bag-placeholder .deck-stack-icon + .kit-item .deck-stack-icon descendant-selector rule: drops color (= stroke via currentColor) to rgba(--quaUser, 0.3) matching the existing .kit-bag-placeholder color (_game-kit.scss:143); drops .deck-stack-icon__card fill to rgba(--quaUser, 0.15) (lower than the stroke alpha — user-dialed 2026-05-25 PM for a subtler look, the cards read as faintly-present "absence" rather than bright-but-grey). 1 new IT in KitBagViewTest (clears equipped_deck → asserts .kit-bag-deck absent, .kit-bag-placeholder present + carries svg.deck-stack-icon + lacks fa-id-badge). Tests: 1 new green; 1298/1298 IT+UT total green (71s; +1 from d26c45b's 1297). Visual verify pending: refresh /gameboard/ + clear equipped deck → kit-bag dialog Deck slot should show a dimmed static card-stack icon matching the dice slot's washed-out look
