 ## Conventions
 
-1. **Composition root is the only place** that names concrete adapters: `StdFileSystem`, `CprHttpClient`, `JsonCollectionRepository<MagicCard>`, `JsonCollectionRepository<PokemonCard>`, `JsonCollectionRepository<YuGiOhCard>`, `JsonCollectionRepository<DigiBattle99Card>`, `JsonSetRepository`, `LocalImageStore`, `LocalPreviewByteCache`, `MagicGameModule`, `PokemonGameModule`, `JapanesePokemonGameModule` (Asia sets/preview backend for unified Pokemon), `YuGiOhGameModule`, `DigiBattle99GameModule`, `MagicGameView`, `PokemonGameView`, `YuGiOhGameView`, `DigiBattle99GameView`, etc. If a concrete adapter type appears anywhere else in the codebase, move the wiring here.
+1. **Composition root is the only place** that names concrete adapters: `StdFileSystem`, `CprHttpClient`, `JsonCollectionRepository<MagicCard>`, `JsonCollectionRepository<PokemonCard>`, `JsonCollectionRepository<YuGiOhCard>`, `JsonCollectionRepository<DigiBattle99Card>`, `JsonSetRepository`, `YuGiOhSetCatalogService`, `DigiBattle99SetCatalogService`, `PokemonSetCatalogService`, `LocalImageStore`, `LocalPreviewByteCache`, `MagicGameModule`, `PokemonGameModule`, `JapanesePokemonGameModule` (Asia sets/preview backend for unified Pokemon), `YuGiOhGameModule`, `DigiBattle99GameModule`, `MagicGameView`, `PokemonGameView`, `YuGiOhGameView`, `DigiBattle99GameView`, etc. If a concrete adapter type appears anywhere else in the codebase, move the wiring here.
 2. **Member declaration order in `CcmApp` matters** — destruction is reverse, so a member that depends on another (e.g. `magicCollSvc_` depends on `magicRepo_` and `imgStore_`; `previewSvc_` depends on `http_` and is consumed by `ctx_`; `magicView_` depends on the typed `magicCollSvc_` and the shared services) must be declared **after** its deps. Do not reorder casually.
 3. **Use `std::unique_ptr` for everything owned** by `CcmApp`. The `AppContext` then holds plain references into those owned objects, plus a vector of `IGameView*` raw pointers (the `unique_ptr<>`s for the views are the actual owners; the vector just describes the active set).
 4. **Game-to-directory mapping** lives in `dirNameForGame(Game)` (anonymous namespace). When adding a new game, extend this function — it is wired into all three repositories (`JsonCollectionRepository`, `JsonSetRepository`, `LocalImageStore`). Pokemon West (`Game::Pokemon`) and Asia (`Game::JapanesePokemon`) both map to `"pokemon"`; `JsonSetRepository` stores their set caches as `sets-west.json` / `sets-asia.json` in that directory (other games keep `sets.json`).

 **Info API:** `https://api.pokemontcg.io/v2/sets`  
 Used by `PokemonSetSource` to fetch all sets. The parser maps `id`, `name`, and `releaseDate` directly into `Set`, then sorts ascending by release date.

+**Asset API:** `https://api.pokemontcg.io/v2/cards` (by id) and `https://api.pokemontcg.io/v2/cards?q=...` (search)  
 Used by `PokemonCardPreviewSource` in two ways:
 
-1. **Preview lookup (`fetchImageUrl`).** Search by `name` plus optional `set.id` and collector number. The parser takes `data[0].images.large` first and falls back to `images.small` if needed.
+1. **Preview lookup (`fetchImageUrl`).** When both set id and collector number are present, prefers `GET /v2/cards/{setId}-{number}` (single-card `data` object) — same idea as Asia’s direct localId fetch — so Lucene `name:` ∩ `number:` misses cannot blank the preview after Auto-detect fills Set #. On HTTP failure or missing images, falls back to a name-less search `set.id:… number:…` (collector numbers are unique within a set). When Set # or set id is missing, keeps the older `name:"…"` search with optional `set.id` / `number`. The parser takes `images.large` first and falls back to `images.small`.
 
-2. **Auto-detect print (`detectFirstPrint` / `detectPrintVariants`, Pokémon edit dialog).** Uses the same endpoint with `name:"<name>"` and `set.id:<setId>` only — **no** `number:` clause — plus `select=name,number,rarity,set` and `pageSize=50` so the response stays small. If the set-scoped HTTP request fails, it retries with **`name:` only** and still filters rows in `PokemonCardPreviewSource::parsePrintVariants(...)` by the picker’s **`set.id`** (not the display set name). The dialog passes `card.set.id` into `CardPreviewService::detectPrintVariants(...)` on a worker thread so the modal stays responsive. Each matching `data[]` row whose **card name matches exactly** (case-insensitive) and whose embedded `set.id` equals the chosen set maps to `AutoDetectedPrint::setNo` as the API `number` field only (for example `25`, not `25/185`). `AutoDetectedPrint::rarity` is filled from the card’s `rarity` field but the Pokémon edit dialog does not auto-sync holo or other flags from it. Distinct `(setNo, rarity)` pairs are deduped. When both an exact card name and `set.id` are supplied, an upstream miss returns an error instead of blending unrelated sets from a broader payload. The edit dialog offers **Auto detect** (fills Set # from the first variant), **Next** (cycles distinct `setNo` values when multiple exist), silent prefetch on **Edit** open, and clears cached variants when **Name** or **Set** changes. The Set # field and persisted `PokemonCard::setNo` keep only the printed-number portion; values such as `4/104` are trimmed to `4` on load and save.

+The preview path normalizes collector numbers before request build. For example, `4/102` is reduced to `4` because the remote `number:` query and card-id path expect only the printed-number component (unquoted `number:4` / `number:TG14`; do not wrap alphanumeric numbers in Lucene quotes when combining with other clauses — that has been observed to 500 on the live API).

+2. A pack checklist at `<dataStorage>/pokemon/set-catalog-west.json` from a paginated `/v2/cards?select=name,number,set&pageSize=250` dump
+
+Each catalog pack stores `id` (pokemontcg.io set id), `name` (display), and `cards[]` of `{ setNo, name }` keyed by the API `number` field (normalized by stripping anything after `/`). Duplicate collector numbers within a pack collapse to one checklist row. The Pokemon **Set Completion** tab reads this file offline; ownership for a West pack requires `PokemonRegion::West`, matching `card.set.id`, and a normalized collector number match. Amount / holo / 1st Edition are ignored for completion counts.

+When previews fail, verify request construction first (name sanitization, number normalization, percent encoding), then verify response shape assumptions: Scryfall (`data`, `image_uris`), Pokemon West (`GET /v2/cards/{setId}-{number}` → `data` object, or search `data[]`; `images.large`/`images.small`; auto-detect also needs `name`, `number`, `rarity`, and `set.id` on each matching row), Yu-Gi-Oh! Yugipedia (`query.pages.<id>.imageinfo[0].url` per filename, missing files tagged `"missing": ""`), Yu-Gi-Oh! YGOPRODeck fallback (`data`, `name`, `card_images`), Digi-Battle digimoncard.io (top-level array with `name`/`id`/`set_name`; CDN `images.digimoncard.io/images/cards/{id}.jpg`), Japanese Pokémon TCGdex (`image` base + `/high.png`; set-detail `cards[]` with `localId`). If the UI fallback path succeeds (network card-back and/or bundled PNG), the panel shows the card-back image and the inline label `(image preview unavailable)`; only if every fallback fails does the preview stay empty with status text.
 
 For Yu-Gi-Oh! specifically, when a printing shows the wrong art compared with Yugipedia’s gallery, debug in this order: (1) verify the candidate list via `YuGiOhCardPreviewSource::buildCandidateFilenames(...)` against the actual file names on Yugipedia’s `Card_Gallery:<Card>` page; (2) confirm the dialog rarity name maps to the expected short code in `ygoRarityShortCode(...)` / `rarityCodeFor(...)` (extend the mapping when a new rarity surfaces); (3) confirm the `firstEdition` flag matches the printed edition stamp — the candidate ordering puts the printed edition first.

 - `card_preview_service_tests.cpp` — `CardPreviewService` registry/orchestration through `registerModule(IGameModule&)` with an inline `FakeGameModule` returning a `FakeSource : ICardPreviewSource` (which carries a `PreviewLookupError::Kind` knob so tests can drive both transient and not-found paths) and a `FixedHttpClient`. Both fakes count `calls` so cache-hit assertions are precise. Pin-downs include: "module returning nullptr is silently skipped", the per-game `detectFirstPrint` / `detectPrintVariants` opt-in guards, and the LRU bytes cache (repeat `fetchPreviewBytes` for the same `(game, name, setId, setNo)` returns the cached payload without touching the source or HTTP; different cards get separate cache slots; transient errors are **not** cached so a flaky connection recovers; `fetchImageBytesByUrl` is keyed by URL and serves the per-game card-back fallback from the same LRU). Production `fetchAndCache` rejects empty HTTP bodies (not exercised by these fakes unless a test sets an empty `body` deliberately). The negative-cache behavior is also pinned down: a `NotFound` source error writes through to the persistent cache *and* short-circuits the next lookup (source not re-invoked); editing a lookup-relevant field invalidates the negative entry automatically; warm-restart (a fresh service over the same cache fake) honors a previously stored negative entry; and a later positive result for the same key replaces the negative entry. The persistent-tier wiring uses an inline `InMemoryByteCache : IPreviewByteCache` fake whose `Entry { negative, payload }` carries the kind explicitly.
 - `local_preview_byte_cache_tests.cpp` — `LocalPreviewByteCache` adapter against `StdFileSystem` (real disk under a unique `temp_directory_path()/ccm_preview_cache_test_*` per case, RAII `TempDir` cleanup; see also `std_file_system_tests.cpp`). Pin-downs: store/load round-trips bytes verbatim; missing key is a clean miss; empty payload is silently skipped; sidecar mismatch (faked hash collision) is treated as a miss so we never serve the wrong card's bytes (or wrong card's negative verdict); the cache survives an adapter restart over the same directory; total-size eviction drops the oldest `.bin` by mtime when a `store` would exceed the cap; a `load` touches the entry's mtime so frequently-viewed cards survive eviction. Negative-entry coverage: `storeNegative` round-trips as `NegativeHit` (not a miss, not a payload, and not counted against the byte cap); negatives survive an adapter restart; a later positive `store` overwrites a previous negative and a later `storeNegative` overwrites a previous positive (releasing its bytes from the cap); and the sidecar collision check applies to negative entries too.
 - `std_file_system_tests.cpp` — `StdFileSystem` directly (`exists`, `isDirectory`, `ensureDirectory`, `readText`, `writeText`, `copyFile`, `remove`, `listDirectory`) under a unique `temp_directory_path()/ccm_std_fs_test_*` directory per case; scope matches the real-disk exception documented for preview-cache tests.

Also `parseCatalog` / `fetchAllWithCatalog` for the set-completion checklist from `cardinfo.php`.
 - `yugioh_set_lookup_tests.cpp` — `lookupYuGiOhSetByShorthand` / helpers in `ccm/util/YuGiOhSetLookup.hpp` (trim, ASCII case-fold, exact `Set.id` match, not-found vs ambiguous).
 - `game_module_tests.cpp` — smoke tests that each concrete `IGameModule` (Magic / Pokemon / Yu-Gi-Oh / DigiBattle99) reports stable `id()`, `dirName()`, `displayName()`, and a non-null `cardPreviewSource()` when constructed with a noop `IHttpClient`.
 - `yugioh_card_preview_source_tests.cpp` — `YuGiOhCardPreviewSource` Yugipedia + YGOPRODeck unit coverage. Helper-level tests pin down `normalizeName` (whitespace + Yugipedia-policy punctuation stripping), `ygoRarityShortCode` + `rarityCodeFor` (CCM3 dialog rarity names → canonical short codes used by both the YGO overview table and Yugipedia filename generation; unknown rarity falls through), `extractSetCode` (`LOB-005` / `LOB-DE005` → `LOB`), `buildCandidateFilenames` (printed-edition first, EN/NA/EU/AU + png/jpg, rarity-less fallback round, empty list when slug or set code is missing), `buildYugipediaQueryUrl` (single `titles=File:A|File:B` batch, percent-encoded), and `parseYugipediaResponse` (returns the URL of the highest-priority filename that resolved, errors when every candidate is `missing`). End-to-end `fetchImageUrl` cases use a `RoutingHttpClient` to verify Yugipedia is queried first and the per-printing scan is returned when found, that empty/error Yugipedia responses fall through to the YGOPRODeck `card_images[0]` fallback, that the YGOPRODeck error is propagated when both upstreams fail, and that an empty `setNo` skips Yugipedia entirely. `parseFirstPrint` preferred-`set_name` lookup is also covered for the auto-detect path. `parsePrintVariants` includes synthetic scenarios aligned with the `yugioh_same_card_set_variant_tests` fixture (dual-rarity vs multi-code within one display set, duplicate suppression, and no merge across unrelated `set_name` rows when the picker label matches nothing).

 ## 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.
-- `include/ccm/ui/MainFrame.hpp` + `src/MainFrame.cpp` — top-level window (default size `1210×770`), menu strip (`File` / `Game` / `Sets` / `Help`), toolbar (Add / Edit / Delete + filter input), and the splitter that swaps the active `IGameView`'s panels. 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/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/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.
 - `include/ccm/ui/SwitchCtrl.hpp` + `src/SwitchCtrl.cpp` — custom pill-track + thumb switch for small modal rows (Yu-Gi-Oh! set picker); fires `EVT_CCM_SWITCH` on user toggle and reads colors from `inferThemeFromWindow` / `paletteForTheme`.
 - `include/ccm/ui/Magic*.hpp` + `src/Magic*.cpp` — Magic implementations: `MagicCardListPanel`, `MagicSelectedCardPanel`, `MagicCardEditDialog`, `MagicGameView`. Each is ~50–100 lines of hook overrides on top of the matching base template.
-- `include/ccm/ui/Pokemon*.hpp` + `src/Pokemon*.cpp` — Pokemon implementations: `PokemonCardListPanel`, `PokemonSelectedCardPanel`, `PokemonCardEditDialog`, `PokemonGameView`. Same shape as the Magic ones; differences are limited to the Set # field, the Holo / 1. Edition flags, and the Pokemon TCG preview lookup key (which includes `setNo`).
+- `include/ccm/ui/Pokemon*.hpp` + `src/Pokemon*.cpp` — Pokemon implementations: `PokemonCardListPanel`, `PokemonSelectedCardPanel`, `PokemonCardEditDialog`, `PokemonGameView`, `PokemonSetCompletionPanel`. Same Add/Edit shape as Magic for the card form; the game view hosts **Single Cards | Set Completion** via `contentPanel` / `hostsOwnLayout` (like Digimon/Yu-Gi-Oh!). Catalog from `PokemonSetCatalogService` (`set-catalog-west.json` / `set-catalog-asia.json`), filled on Update Pokemon. The Add/Edit/Delete + filter toolbar lives inside the Single Cards tab; MainFrame hides its shared toolbar while Pokemon is active.
+- `include/ccm/ui/DigiBattle99*.hpp` + `src/DigiBattle99*.cpp` — Digimon Digi-Battle: list/selected/edit plus `DigiBattle99GameView` via `contentPanel` with a **palette-painted tab strip** + `wxSimplebook` (**Single Cards** | **Set Completion**) — not native `wxNotebook`, which stays light on MSW dark mode — and `DigiBattle99SetCompletionPanel` (pack progress tiles + greyed checklist). Catalog from `DigiBattle99SetCatalogService` (`set-catalog.json`), filled on Update Sets. The Add/Edit/Delete + filter toolbar lives **inside** the Single Cards page; MainFrame hides its shared toolbar while Digimon is active (`hostsOwnLayout`).
+- `include/ccm/ui/YuGiOh*.hpp` + `src/YuGiOh*.cpp` — Yu-Gi-Oh!: list/selected/edit plus `YuGiOhGameView` notebook (**Single Cards** | **Set Completion**) via the same `hostsOwnLayout` / `contentPanel` pattern as Digimon, and `YuGiOhSetCompletionPanel`. Catalog from `YuGiOhSetCatalogService` (`yugioh/set-catalog.json`), filled on Update Sets from YGOPRODeck `cardinfo.php`.
 - `include/ccm/ui/SvgIcons.hpp` + `src/SvgIcons.cpp` — embedded SVG templates with a `@FILL@` placeholder. Magic flags: `kSvgFoil` / `kSvgSigned` / `kSvgAltered`. Pokemon flags: `kSvgHolo` (sparkle, mirroring the original `IconHolo` from `PokemonTable.tsx`) and `kSvgFirstEdition` (themed "1" inside an outlined badge, rebuilt from the original `IconPokemonFirstEdition.tsx` — every fill/stroke uses `@FILL@` so the icon themes alongside the others). Toolbar glyphs: `kSvgToolbarAdd` / `kSvgToolbarEdit` / `kSvgToolbarDelete` (vscode-codicons). `svgIconBitmap` / `paddedSvgIcon` helpers backed by `wxBitmapBundle::FromSVG`. Bitmaps from `svgIconBitmap` go straight to `wxStaticBitmap` / `wxBitmapButton::SetBitmap` cleanly; for the row-icon path `IconListCtrl` packs them into a private premultiplied-BGRA `HIMAGELIST` and draws with `ImageList_Draw`. See convention 11 for the full pitfall write-up.
 - `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`.

 3. **Ownership**: dialogs and panels are heap-allocated and parented to a `wxWindow`. wxWidgets owns the lifetime — do **not** wrap them in `unique_ptr`. `IGameView` instances themselves are owned by `app/main.cpp` (`std::unique_ptr<>`); the panels owned by the views become children of the `MainFrame` splitter on first mount.
 4. **Custom events**: `EVT_CARD_SELECTED` is fired by the list panel on itself (not its parent). Each `IGameView` binds it on its typed list panel inside the panel's first construction so the typed selection flows directly into the typed selected panel — `MainFrame` never sees a `MagicCard` or a `PokemonCard`. Do not move that binding back into `MainFrame`.
 5. **wxFont modifications** mutate in place: `font.MakeBold().MakeLarger()` — do not call `Scale` (it does not exist on wxFont 3.2; use `MakeLarger` / `SetPointSize`).
-6. **Single-active-game UX.** `MainFrame` only ever shows one game's panels at a time; the splitter swaps `listPanel()` / `selectedPanel()` when the user picks a different `Game` menu entry. Do not stand up parallel side-by-side tabs for different games.
+6. **Single-active-game UX.** `MainFrame` only ever shows one game's panels at a time; the content host swaps either the shared `listPanel()` / `selectedPanel()` splitter or a game’s `contentPanel()` when the user picks a different `Game` menu entry. Do not stand up parallel side-by-side tabs for different games. Digimon’s, Yu-Gi-Oh!’s, and Pokémon’s Single Cards / Set Completion switch is an in-game mode switch (themed tab strip + `wxSimplebook`), not multi-game tabs.
 7. **No `ccm_warnings`.** This target intentionally does **not** link the strict warning interface — wxWidgets headers trip `-Wpedantic` / `-Wshadow`. Keep it that way; do not add the link.
 8. **Async background work** must not capture `this` raw. Use the pattern from `BaseSelectedCardPanel`: a `std::shared_ptr<State>` holding `std::atomic<bool> alive`, `std::atomic<unsigned> currentGen`, and a back-pointer to the panel; spawn a detached `std::thread`, then deliver the result with `wxTheApp->CallAfter([state, gen, ...]() { if (!state->alive) return; if (state->currentGen != gen) return; ... })`. Flip `alive=false` in the panel destructor so late callbacks become no-ops.
 9. **Icons come from `SvgIcons.hpp`.** Don't inline new SVG strings in panel sources; add them to `SvgIcons.{hpp,cpp}` so all panels stay in sync. Always pass a runtime fill color (`wxSystemSettings::GetColour(...).GetAsString(wxC2S_HTML_SYNTAX)`); never bake one into the SVG.
