 Interactions (research 09 §1.2 / §5, which supersede the first draft): shop card, upgrade and 机变 card are two-tap (select → confirm, §18.2) — a tap anywhere on the card, its confirm strip included, is the card's tap (shop cards have no ⓘ corner; the armed bar sits above the detail card; a shop card that cannot be bought right now opens its detail on tap, §20.7); a press / drop goes by the tile under the pointer (§18.1); drag bench↔board — over a legal tile the dragged unit stands on it, as in the official deploy drag, held under the pointer elsewhere (§27.62); a legal board drop (also onto the piece's own tile) opens the 4-direction deploy wheel (swipe UP/RIGHT/DOWN/LEFT with the rotated range striped orange; release in the centre, ✕ 点击取消 or Esc cancels); tap a unit's tile ⇒ underframe with **出售 +N** (and **撤退** on the board; items/Arts in the hand / temp: **销毁** — equipped items are locked, §6.2) plus its rotated range — the range follows the open detail card (`screens/game/range.js inspectRange`, GitHub PR #281): an own board piece in prep, and in battle or on a scouted board any ally operator / summon on the field with its current range (the live stats' `range` and `dir`, the snapshot's tile), never an enemy or a bench unit (UnitInfo `area` hand / temp); drag, the wheel and the pen hide it; no drag-to-sell; drag an item onto a unit's tile ⇒ equip that unit (both slots used ⇒ the replace dialog `ui/equipReplace.js` shows the incoming and the two equipped items; the player picks the one to replace — it is destroyed — `g.equip replaceUid`; cancel changes nothing); Arts are dropped on a tile and get the direction step; right-click or long-press ⇒ detail (or a tap on a shop card while the bar is locked); keyboard shortcuts — the defaults, which each player rebinds in 设置 → 快捷键 (`ui/gameLogic/shortcuts.js`, saved with the settings; §25.15) — `R` refresh, `F` freeze, `D` level-up, `Q` retreat / `X` sell the selected operator, `Space` ready (in a solo battle: pause / resume, §14 Solo pause); `Esc` closes (fixed); none acts while a text field has the focus or a dialog is open. All actions optimistic-free: UI waits for server state (latency is small).
