+## Wolfskin Home
+
+Home is one lazy frame: a non-rotating resume → Next up → newest → pick hero,
+Jellyfin shelves, per-destination "Your …" shelves and the Discover continuation.
+The final action opens the real merged Discover screen at its top through the
+shell's root re-selection transition. Home's See all cards open `WolfskinSeeAllLists`, carrying
+the complete underlying list rather than the visible shelf window. Title content
+remains the later-slice target.
+
+All Home components and immutable screen models live in `:wolfskin-design`.
+The shell's remembered view owns vertical position, each row's selected card and
+actual horizontal `LazyListState`, and the bounded six-hour ratings session cache.
+Composing destinations bind `rememberedView(route)` before navigation effects run, so a
+new See all grid cannot borrow or clamp Home's scroller. Re-entry restores the
+remembered track before the page with `scrollToItem`, preserving exact indices and
+pixel offsets rather than animating back. Android focus stays with the shell;
+cards use its logical focus, without requests against uncomposed lazy items.
+Back preserves the viewport; returning to Home does not re-run focus-follow over
+a manually scrolled saved view. The next arrow re-enters visible content when
+scrolling moved focus off-screen.
+Pointing changes focus without activation, cards activate on key-up, and held
+OK events cannot activate twice.
+Between shelves, an unvisited row selects the nearest visible card center even
+when card widths differ. A visited row restores its column. Horizontal movement
+keeps the track still while focus remains in its visible middle.
+The initial skeleton parks focus on the nav. When the first content arrives,
+an untouched fresh entry focuses hero button zero; intervening nav input prevents
+that automatic transfer. Home, Libraries and Discover use the same `ShellContentFocus`
+release/repeat guard and Back ladder.
+
+`HomeReadFacade` is the only Home code importing Jellyfin API clients. Release
+variants read the selected user's Resume, Next up, newest titles and destination
+shelves, with app-private last-known-good projections through the shared atomic
+disk cache. A missing saved library becomes a recovery panel; a saved library
+stays visible when Jellyfin is unreachable. Playback resolves an actual film or
+episode and checks Jellyfin before opening upstream's player. No season,
+recommendation stub or different person's session is promoted to playback.
+An unresolved person switch shows the same sign-in guard for Home as for native
+library content, before mounting Home's source reads.
+
+Debug variants additionally package the locked fixture and local artwork under
+`wolfskin-design/src/debug/assets/wolfskin-home/`; release variants exclude them.
+The fixture provider supplies the approved household data and Home states without
+network reads in tests. Conductarr sign-in is not implemented here: real signed-out
+Home hides every rating and shows "Discover needs sign-in". No Seerr fallback is
+used. Catalogue data and ratings in debug captures are fixture-backed.
+
+Home, Libraries and Discover reuse `TitleCard`, `Caption` and `LibrarySeeAllCard`;
+those screens and Requests share one `WolfskinImages` loader. Exact-slot requests use RGB565 for posters,
+disable crossfades, share a 64 MiB memory/128 MiB disk cache, limit image work to
+four reads and prefetch the next shelf. Rating plates start at 14 sp, shrink to 12 sp
+and drop trailing entries rather than wrap. Their uncached read gate is 350 ms;
+cached focus returns without that delay.
+
+Focus rings and native lift draw outside fixed slots. The Saved nav chip uses its
+own geometry; the Discover section uses a warning pill. Caption separators multiply
+the existing muted colour alpha by the shared 40% token. Home-only untrimmed styles
+and `exactLineBox` honor the declared CSS line boxes despite Android's intrinsic
+paragraph minimums; shell and library typography retain their existing defaults.
+The shared See all component uses its canonical locked 8px gap, not the generic
+10px tail spacing. Focus lifts use the merged draw-only `FocusLift` implementation;
+the obsolete Home shadow helper and duplicate gap/lift measurements are removed.
+Vertical moves clamp to short target rows, including a final See all card.
+
+`make test` includes `HomeCaptureTest` (23 native acceptance states) and the
+data-driven paths in `wolfskin-home-presses.json`: play next 2, resume 3, Discover
+4, deep-row Back/Down 9, Trending 13 and Trending's See all card 33 presses.
+Home captures are written to `build/wolfskin-captures/home/`. Compare those images
+side by side with the frozen spec captures; Compose Roboto/JPEG rasterisation,
+the approved button-scale consolidation and removal of prototype sample pills
+are recorded differences, not a claim of browser pixel equality.
