 ## Layer pointers
 
 - `include/ccm/ui/AppContext.hpp` — the boundary type. A struct of references to shared core services + per-game modules and a `std::vector<IGameView*>` of all UI bundles. UI code talks to core only through this struct (and the typed pointers go through `IGameView`, never directly).
-- `include/ccm/ui/IGameView.hpp` — abstract base class for per-game UI bundles. `MainFrame` only ever sees `IGameView` references; this is the seam that lets the frame swap between Magic, Pokemon, and any future TCG without knowing their card types. Optional `contentPanel` / `hostsOwnLayout` / `contentPanelIfCreated` let Digimon, Yu-Gi-Oh!, and Pokemon own a tabbed layout without changing Magic’s splitter mounting.
-- `include/ccm/ui/MainFrame.hpp` + `src/MainFrame.cpp` — top-level window (default size `1210×770`), menu strip (`File` / `Game` / `Sets` / `Help`), shared toolbar (Add / Edit / Delete + filter input; hidden via `toolbarPanel_` when `hostsOwnLayout()`), and a `contentHost_` that either shows the shared splitter (Magic) or a game’s `IGameView::contentPanel` (Pokémon / Yu-Gi-Oh! / Digimon Digi-Battle notebooks). The `Game` and `Sets` menus are built dynamically from `AppContext::gameViews` so adding a new game lights up its menu entries automatically. Filter and toolbar actions forward to `activeView()`. `EVT_PREVIEW_STATUS` (preview fetch outcome → status label; empty string resets to `"Ready"`) is the only event the frame binds; `EVT_CARD_SELECTED` is bound *per view* (each `IGameView` connects its typed list panel to its typed selected panel internally). About is a custom themed dialog (not `wxAboutBox`) so dark mode behavior stays consistent.
-- `include/ccm/ui/BaseCardListPanel.hpp` — header-only template `BaseCardListPanel<TCard, TSortColumn>` that owns ALL the non-game-specific `wxListCtrl` machinery: hidden zero-width spacer column (legacy of the MSW comctl32 image-list gutter workaround, kept to preserve column-index math), themed header row (clickable to sort, edge-drag to resize, divider double-click to autosize), per-icon-column cached `wxBitmap` pairs (normal + selected color) consumed by `IconListCtrl::MSWOnNotify` so row icons are pixel-perfect centered under the themed-header icons, rebuild guard so DESELECTED/SELECTED storms collapse into a single bubbled `EVT_CARD_SELECTED`, case-insensitive substring filter via `setFilter(...)`, per-column toggle-direction sort. Subclasses fill in column descriptors + per-row text + per-icon-column flag predicates + dispatch hooks (`sortBy`, `matchesFilter`).
+- `include/ccm/ui/IGameView.hpp` — abstract base class for per-game UI bundles. `MainFrame` only ever sees `IGameView` references; this is the seam that lets the frame swap between Magic, Pokemon, and any future TCG without knowing their card types. Optional `contentPanel` / `hostsOwnLayout` / `contentPanelIfCreated` let Digimon, Yu-Gi-Oh!, and Pokemon own a tabbed layout without changing Magic’s splitter mounting. `attachSharedToolbarEdit` lets Magic wire MainFrame’s Edit button for multi-select hide/show; hostsOwnLayout games manage their own Edit button via `setToolbarEditVisible`.
+- `include/ccm/ui/MainFrame.hpp` + `src/MainFrame.cpp` — top-level window (default size `1210×770`), menu strip (`File` / `Game` / `Sets` / `Help`), shared toolbar (Add / Edit / Delete + filter input; hidden via `toolbarPanel_` when `hostsOwnLayout()`), and a `contentHost_` that either shows the shared splitter (Magic) or a game’s `IGameView::contentPanel` (Pokémon / Yu-Gi-Oh! / Digimon Digi-Battle notebooks). The `Game` and `Sets` menus are built dynamically from `AppContext::gameViews` so adding a new game lights up its menu entries automatically. Filter and toolbar actions forward to `activeView()`. Edit is hidden when more than one list row is selected. `EVT_PREVIEW_STATUS` (preview fetch outcome → status label; empty string resets to `"Ready"`) is the only event the frame binds; `EVT_CARD_SELECTED` is bound *per view* (each `IGameView` connects its typed list panel to its typed selected panel internally).

+- `include/ccm/ui/BaseCardListPanel.hpp` — header-only template `BaseCardListPanel<TCard, TSortColumn>` that owns ALL the non-game-specific `wxListCtrl` machinery: hidden zero-width spacer column (legacy of the MSW comctl32 image-list gutter workaround, kept to preserve column-index math), themed header row (clickable to sort, edge-drag to resize, divider double-click to autosize), per-icon-column cached `wxBitmap` pairs (normal + selected color) consumed by `IconListCtrl::MSWOnNotify` so row icons are pixel-perfect centered under the themed-header icons, rebuild guard so DESELECTED/SELECTED storms collapse into a single bubbled `EVT_CARD_SELECTED`, case-insensitive substring filter via `setFilter(...)`, per-column toggle-direction sort. **Multi-select** is enabled (no `wxLC_SINGLE_SEL`): Ctrl toggles rows, Shift selects a range; `selected()` / `selectedCount()` / `selectedCards()` expose the selection; rebuild/sort/filter preserve all selected ids; Ctrl+C copies every selected row as TSV (one line per card). Subclasses fill in column descriptors + per-row text + per-icon-column flag predicates + dispatch hooks (`sortBy`, `matchesFilter`).
 - `include/ccm/ui/IconListCtrl.hpp` + `src/IconListCtrl.cpp` — small `wxListCtrl` subclass that intercepts `NM_CUSTOMDRAW` on Windows and paints flag-icon sub-items at the exact center of each cell. It owns a `HIMAGELIST` (built from the cached `wxBitmap` pairs via straight-RGBA 32 bpp DIB sections) and draws each cell's icon with `ImageList_Draw(ILD_TRANSPARENT)` onto the native `HDC` from `NMLVCUSTOMDRAW`. This is the same low-level pixel path `wxImageList` uses internally, which is the only rendering path that has reliably preserved SVG transparency + correct fill color across light/dark themes on MSW. Two earlier attempts — `wxGraphicsContext::DrawBitmap` and a manually-premultiplied-DIB `AlphaBlend` — both rendered runtime-fill SVG icons as solid white in light mode and were abandoned (see convention 11). The custom-draw is purely about positioning; pixel format handling is delegated to comctl32.
 - `include/ccm/ui/BaseSelectedCardPanel.hpp` — header-only template `BaseSelectedCardPanel<TCard>` that owns the right-hand-side detail panel: preview image fetched via `CardPreviewService` (with the `shared_ptr<State>` + `std::atomic alive`/`currentGen` cancellation pattern), 2-column detail grid, flag-icon strip that collapses when no flags are set, image list with double-click viewer. If preview lookup fails or returns empty bytes, the panel loads a per-game **card-back fallback**: Magic and Pokémon West use fixed HTTPS URLs (`fallbackImageUrlForGame`, CCM2-aligned); **Pokémon Asia** uses the Japanese TCG back via `previewGameFor(card)` → `Game::JapanesePokemon`; **Yu-Gi-Oh!** tries Yugipedia thumbnail URL, then full `Back-EN.png` on `ms.yugipedia.com`, then reads `<exeDir>/assets/ygo_card_back.png`; **Digimon Digi-Battle** reads `<exeDir>/assets/digibattle99_card_back.png` (both bundled assets copied by `app/CMakeLists.txt` on link). The constructor caches `<exeDir>/` for that disk path. Subclasses describe the detail rows / flag icons / preview lookup `(name, setId, setNo)` and own a `Game` constant; override `previewGameFor` when preview routing differs from collection `gameId()` (Pokemon West/Asia).
 - `include/ccm/ui/BaseCardEditDialog.hpp` — header-only template `BaseCardEditDialog<TCard>` that owns the standard Add/Edit form: Name, optional `appendPreSetRows` (Pokemon West/Asia region), Set picker (read-only `wxComboBox` with typeahead — prefix first, then substring, ASCII-fold so `Pokemon`/`Jungle` match `Pokémon Jungle` — and case-insensitive id matching for legacy data), Amount spin, Language and Condition choices (`languagesForChoice()` hook; Pokemon filters by region), Note, image management (Add multiple via `wxFD_MULTIPLE`, Remove, double-click to view), OK/Cancel + validation. The **Set** row is built on a host `wxPanel` with a horizontal `wxBoxSizer`; games may override `customizeSetPickerRow(row, combo)` to wrap the combo (default: combo only). After a programmatic selection, `applySetSelectionByIndex` updates `card_.set` and calls `onSetSelectionApplied()` (default no-op). After `buildAndPopulate()`, the template snapshots the loaded card into `openingSnapshot_`; in **`EditMode::Edit`**, OK asks **Yes/No** (“Save changes to this card?”) only when the card differs from that snapshot (dirty-only confirm). **Create** mode never prompts. Subclasses build the flags row (`buildFlagsRow`), append game-specific extra rows (e.g. Pokemon's `Set #`) via `appendExtraRows`, and copy values in/out of the typed card (`readExtraFromCard` / `writeExtraToCard`). The template binds `EVT_TEXT` on **Name** and invokes `onCardLookupContextChanged()` so games can drop stale keyed metadata when the user edits the lookup identity (Yu-Gi-Oh! clears its YGOPRODeck print-variant cache here). `YuGiOhCardEditDialog` overrides `customizeSetPickerRow` to add a **`SwitchCtrl`** pill switch plus a **hint** label (`Set name` / `Set code`), a text field, and **Auto detect** (resolves `Set.id` via `ccm/util/YuGiOhSetLookup.hpp` against `availableSets()`, then returns to the dropdown on success); it overrides `onSetSelectionApplied` to match manual set-change behavior. It additionally `CallAfter`s a silent `detectPrintVariants` when opening **Edit** (and after changing **Set**) so multi-print **Next** buttons can appear without pressing Auto detect first, as long as name + display set are populated. The base also exposes helpers to sync current control values and inspect the currently-selected set when a subclass needs derived-field UI.

 - `src/BaseEvents.cpp` — single-translation-unit definitions for `EVT_CARD_SELECTED` and `EVT_PREVIEW_STATUS`. Both events are template-instantiation-agnostic so all per-game panels share the same event types.
 - `include/ccm/ui/SettingsDialog.hpp` + `src/SettingsDialog.cpp` — edits `Configuration` via `ConfigService::store`.
 - `include/ccm/ui/ImageViewerDialog.hpp` + `src/ImageViewerDialog.cpp` — full-size viewer with prev/next.
-- `include/ccm/ui/Theme.hpp` + `src/Theme.cpp` — shared theme helpers and popup helpers (`showThemedMessageDialog`, `showThemedConfirmDialog`) for consistent dark/light dialogs. `applyThemeToWindowTree` paints `wxButton`, `wxBitmapButton`, and **`wxToggleButton`** in dark mode (custom `wxEVT_PAINT` + hover/focus) so native Win32 theming cannot flash a light hover plate; light mode leaves buttons native where possible. `SwitchCtrl` is palette-driven and self-painted (not native `wxToggleButton`).

     - Auto-detect actions in edit dialogs (e.g. detect set print number / rarity from API) are opt-in per game.
     - Keep shared templates game-agnostic: put buttons and detection behavior in `<Name>CardEditDialog`, not in `BaseCardEditDialog`. Yu-Gi-Oh!'s **Set code** entry (`SwitchCtrl` + text + **Auto detect** against cached sets) is wired through the template hook `customizeSetPickerRow` so Magic/Pokemon keep the default single-combo row unchanged.
     - For games that use composed print IDs (prefix + numeric suffix), allow user editing on the numeric portion and render the full code as a read-only derived label beside the input.
+    - Bidirectional identify (Yu-Gi-Oh!, Bandai, Pokémon West/Asia, Digi-Battle): Set is always required. Set # **Auto detect** fills set number from Name, or fills Name from Set #. When **both** fields are filled, the field the user last typed is the lookup key (`CardLookupEditField` / `preferDetectBySetNo` in `ccm/util/CardLookupDetect.hpp`, tracked by `BaseCardEditDialog::markNameLookupEdited` / `markSetNoLookupEdited`). Programmatic `ChangeValue` from a detect result does not flip the key.
