fix(recipe): View-Beacon ueber \$effect statt onMount

Live-Test auf kochwas-dev: bei Hard-Reload/Cold-Start (nicht SPA-Click) landete kein view-Eintrag in der DB. Ursache: Recipe-Page-onMount feuert vor Layout-onMount, profileStore.load() laeuft aber im Layout- onMount und macht erst danach einen async fetch — zum Zeitpunkt des Beacons war profileStore.active noch null. Loesung: Beacon im \$effect, das auf profileStore.active reagiert. viewBeaconSent-Flag verhindert duplicate POSTs wenn der User waehrend der Page-Lifetime das Profil wechselt — der ursprueglich getrackte Profil-View bleibt der "richtige" fuer dieses Page-Open.

fix(home): focus-visible auf section-head + scoped chev-CSS

+# Einkaufsliste — Design-Spec
+
+**Datum**: 2026-04-21
+**Status**: Spec, vor Implementierung
+
+## Ziel
+
+Aus Rezepten auf der Wunschliste eine flache, aggregierte Einkaufsliste erzeugen. Die Liste ist haushaltsweit geteilt, mobil-first, im Supermarkt abhakbar. Portionen sind pro Rezept anpassbar. Identische Zutaten (gleicher Name + gleiche Einheit) werden über mehrere Rezepte hinweg summiert.
+
+## Entscheidungen (aus Brainstorming)
+
+| Thema | Entscheidung |
+|---|---|
+| Sichtbarkeit | Global, eine Liste für alle Profile |
+| Portionen | Default `servings_default` beim Hinzufügen; zentral auf der Einkaufslisten-Seite anpassbar |
+| Aggregation | Flache Liste, exaktes Matching auf `(LOWER(TRIM(name)), LOWER(TRIM(unit)))`. Keine Fuzzy-Matches — lieber zwei Zeilen als falsche Summen. Rezept-Herkunft pro Zeile sichtbar. |
+| Abhaken | Checkbox, durchgestrichen, sortiert ans Ende. Manuelles Cleanup via „Erledigte entfernen" / „Liste leeren" |
+| Kopplung | Komplett entkoppelt von Wunschliste und `cooking_log`. Abhaken beeinflusst nur die Einkaufsliste. |
+| Header-Badge | Zählt **nicht-abgehakte** aggregierte Zutaten-Zeilen. Versteckt sich bei Count = 0. |
+| Manuelle Einträge | Out of scope. Nur rezeptbasiert. |
+
+## Datenmodell
+
+Migration `013_shopping_list.sql`:
+
+```sql
+CREATE TABLE shopping_cart_recipe (
+  recipe_id INTEGER PRIMARY KEY REFERENCES recipe(id) ON DELETE CASCADE,
+  servings INTEGER NOT NULL,
+  added_by_profile_id INTEGER REFERENCES profile(id) ON DELETE SET NULL,
+  added_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE TABLE shopping_cart_check (
+  name_key TEXT NOT NULL,
+  unit_key TEXT NOT NULL,
+  checked_at TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
+  PRIMARY KEY (name_key, unit_key)
+);
+```
+
+**Derivation-Prinzip**: Die aggregierte Liste wird **nicht materialisiert**. Sie wird bei jedem Lesen aus `shopping_cart_recipe JOIN recipe JOIN ingredient` plus Skalierungs-Faktor berechnet. Vorteil: Rezept-Edits wirken live auf die Liste.
+
+**Abhaken pro aggregierter Zeile**: `(name_key, unit_key)` — nicht pro Rezept-Zutat. Wenn zwei Rezepte beide „Mehl, g" haben, gibt es eine Zeile „400 g Mehl", und ein Haken reicht. Wird eines der Rezepte entfernt, bleibt „200 g Mehl" mit Haken sichtbar.
+
+**Orphan-Checks** (aggregierter Schlüssel ist nicht mehr durch ein Rezept im Cart abgedeckt): Werden nicht aktiv gelöscht, tauchen aber in der Ausgabe von `listShoppingList` nicht auf (der Join erzeugt keine Zeile). Späteres Cleanup optional via `clearCart` / `clearCheckedItems`.
+
+### Aggregations-SQL (Kern)
+
+```sql
+SELECT
+  LOWER(TRIM(i.name)) AS name_key,
+  LOWER(TRIM(COALESCE(i.unit, ''))) AS unit_key,
+  MIN(i.name) AS display_name,
+  MIN(i.unit) AS display_unit,
+  SUM(i.quantity * cr.servings * 1.0 / r.servings_default) AS total_quantity,
+  GROUP_CONCAT(DISTINCT r.title) AS from_recipes,
+  EXISTS(SELECT 1 FROM shopping_cart_check c
+         WHERE c.name_key = LOWER(TRIM(i.name))
+           AND c.unit_key = LOWER(TRIM(COALESCE(i.unit, '')))) AS checked
+FROM shopping_cart_recipe cr
+JOIN recipe r ON r.id = cr.recipe_id
+JOIN ingredient i ON i.recipe_id = r.id
+GROUP BY name_key, unit_key
+ORDER BY checked ASC, display_name COLLATE NOCASE;
+```
+
+**Edge Cases**:
+- `i.quantity IS NULL` → `total_quantity` bleibt NULL, UI rendert ohne Mengenangabe.
+- `r.servings_default IS NULL` → Division through-by-NULL → `total_quantity` NULL; defensiver: `COALESCE(r.servings_default, cr.servings)` (Faktor = 1, wenn kein Default bekannt).
+- `i.unit IS NULL` → `unit_key = ''`, Anzeige ohne Einheit.
+- Rezept hat keine Zutaten (sehr selten) → kein Beitrag zur Liste, Rezept-Chip erscheint trotzdem (Signal: „ups, keine Zutaten").
+
+## Server-Module
+
+### `src/lib/server/shopping/repository.ts`
+
+Neue Typen:
+
+```ts
+export type ShoppingCartRecipe = {
+  recipe_id: number;
+  title: string;
+  image_path: string | null;
+  servings: number;
+  servings_default: number;
+};
+
+export type ShoppingListRow = {
+  name_key: string;
+  unit_key: string;
+  display_name: string;
+  display_unit: string | null;
+  total_quantity: number | null;
+  from_recipes: string;  // comma-separated recipe titles
+  checked: 0 | 1;
+};
+
+export type ShoppingListSnapshot = {
+  recipes: ShoppingCartRecipe[];
+  rows: ShoppingListRow[];
+  uncheckedCount: number;
+};
+```
+
+Funktionen:
+
+- `addRecipeToCart(db, recipeId, profileId, servings?)` — `INSERT … ON CONFLICT(recipe_id) DO UPDATE SET servings = excluded.servings`. Wenn `servings` fehlt, nimmt `COALESCE(recipe.servings_default, 4)`.
+- `removeRecipeFromCart(db, recipeId)`
+- `setCartServings(db, recipeId, servings)` — App-seitig validiert: `1 ≤ servings ≤ 50`. SQL-Level `CHECK (servings > 0)` zusätzlich als Sicherheitsnetz.
+- `listShoppingList(db) → ShoppingListSnapshot` — liefert Cart-Rezepte, aggregierte Zeilen und `uncheckedCount` in einer Transaktion.
+- `toggleCheck(db, nameKey, unitKey, checked: boolean)` — Insert bzw. Delete in `shopping_cart_check`.
+- `clearCheckedItems(db)` — transaktional:
+  1. Aggregation laufen lassen und `recipe_id`s finden, deren sämtliche aggregierten Zeilen abgehakt sind (ein Rezept zählt als „erledigt", wenn all seine `(name_key, unit_key)`-Beiträge in `shopping_cart_check` stehen)
+  2. Diese Rezepte via `DELETE FROM shopping_cart_recipe WHERE recipe_id IN (…)` entfernen
+  3. Check-Einträge, die jetzt keinen Bezug mehr haben, mit `DELETE FROM shopping_cart_check WHERE (name_key, unit_key) NOT IN (<aktive Keys nach Step 2>)` aufräumen
+- `clearCart(db)` — `DELETE FROM shopping_cart_recipe; DELETE FROM shopping_cart_check;`
+
+### Routen
+
+| Methode + Pfad | Body/Params | Zweck |
+|---|---|---|
+| `GET /api/shopping-list` | — | Snapshot holen |
+| `POST /api/shopping-list/recipe` | `{ recipe_id, servings?, profile_id? }` | Rezept in Cart; idempotent |
+| `PATCH /api/shopping-list/recipe/:recipe_id` | `{ servings }` | Portionen ändern |
+| `DELETE /api/shopping-list/recipe/:recipe_id` | — | Rezept raus |
+| `POST /api/shopping-list/check` | `{ name_key, unit_key }` | Abhaken |
+| `DELETE /api/shopping-list/check` | `{ name_key, unit_key }` | Haken weg |
+| `DELETE /api/shopping-list/checked` | — | Erledigte entfernen |
+| `DELETE /api/shopping-list` | — | Liste leeren |
+
+Error-Handling: 404 wenn `recipe_id` nicht im Cart (nur bei DELETE/PATCH auf spezifischem Rezept), 400 bei Validation-Fehlern (servings ≤ 0, fehlende Felder), 500 mit JSON-Body `{ message }` bei DB-Fehlern.
+
+## Client-Store
+
+`src/lib/client/shopping-cart.svelte.ts` — analog zu `wishlist.svelte.ts`:
+
+```ts
+class ShoppingCartStore {
+  uncheckedCount = $state(0);
+  recipeIds = $state<Set<number>>(new Set());  // für „ist dieses Rezept im Cart?"
+  loaded = $state(false);
+
+  async refresh(): Promise<void>;
+  async addRecipe(recipeId: number): Promise<void>;
+  async removeRecipe(recipeId: number): Promise<void>;
+  isInCart(recipeId: number): boolean;
+}
+```
+
+- `refresh()` ruft `GET /api/shopping-list` auf und extrahiert `recipeIds` + `uncheckedCount` aus dem Snapshot. Ein separater Leichtgewichts-Count-Endpoint ist nicht nötig; der Snapshot ist klein.
+- Store wird in `+layout.svelte` beim `onMount` initialisiert (wie `wishlistStore.refresh()`).
+- Nach jedem Mutating-Call (add/remove/toggle/clear) wird `refresh()` vom aufrufenden Code getriggert.
+
+## UI
+
+### (a) Wunschlisten-Karte — Relayout
+
+Aktuell drücken zwei rechts-gestapelte Buttons den Titel-Text auf Handys zusammen. Neues Layout:
+
+```
+┌──────────┬─────────────────────────────┐
+│          │  [Utensils|3] [Cart] [Trash] │   Action-Leiste oben, horizontal
+│   Bild   │  Titel (fett, 2 Zeilen max)  │
+│   96px   │  Hendrik, Verena, Leana      │   wanted_by + ★
+│          │  ★ 4.5                        │
+└──────────┴─────────────────────────────┘
+```
+
+Konkret in `src/routes/wishlist/+page.svelte`:
+- `.actions` wird horizontal, als erste Zeile über dem Titel rechts-bündig.
+- `source_domain`-Span aus der `.meta`-Zeile entfernt (Platz).
+- Neuer Cart-Button zwischen Utensils und Trash:
+  - Nicht im Cart: neutral (Icon grau), aria-label „In den Einkaufswagen"
+  - Im Cart: grün gefüllt, Häkchen-Badge unten rechts, aria-label „Aus Einkaufswagen entfernen"
+- Alle drei Buttons ≥ 44 × 44 px (mobile Tap-Target).
+
+Vergleichbare Reorg in `src/routes/recipes/[id]/+page.svelte` nötig? — **Nein**. Der Cart-Button erscheint nur auf der Wunschliste. (Begründung: Rezept-Detail hat schon ein volles Action-Menü; das Hinzufügen zum Cart passiert bewusst aus der Wunschlisten-Perspektive.)
+
+### (b) Header-Badge
+
+`src/routes/+layout.svelte` — rechts neben dem bestehenden Kochtopf-Icon:
+
+- Icon `ShoppingCart` aus `lucide-svelte`
+- Badge-Kreis oben rechts mit `shoppingCartStore.uncheckedCount`
+- Nur sichtbar wenn `uncheckedCount > 0`
+- Klick → `goto('/shopping-list')`
+- Gleicher Visual-Style wie der CookingPot (Farb-Konsistenz grün)
+
+### (c) Seite `/shopping-list`
+
+Datei: `src/routes/shopping-list/+page.svelte`
+
+```
+┌──────────────────────────────────────┐
+│ Einkaufsliste                        │   Header
+│ 12 noch zu besorgen · 3 Rezepte      │
+├──────────────────────────────────────┤
+│ [Carbonara 4p- +] [Lasagne 6p- +] …  │   Rezept-Chips, horizontal scrollbar
+│                                       │   (Titel + Portions-Stepper + X)
+├──────────────────────────────────────┤
+│ ☐ 400 g Mehl                         │
+│    aus Carbonara, Lasagne             │
+│ ☐ 6 Stk Eier                          │
+│    aus Carbonara                      │
+│ …                                     │
+│ ☑ 200 g Butter  (durchgestrichen)     │   Abgehakt, ans Ende
+├──────────────────────────────────────┤
+│ [Erledigte entfernen] [Liste leeren] │   Sticky Footer
+└──────────────────────────────────────┘
+```
+
+**Komponenten** (neue Svelte-Dateien):
+- `src/lib/components/ShoppingCartChip.svelte` — Rezept-Chip mit Stepper + Remove
+- `src/lib/components/ShoppingListRow.svelte` — eine Zutatenzeile mit Checkbox
+
+**Portions-Stepper**: - und + Buttons, mittig die Zahl. Min 1, Max 50 (sanity). Klick sendet PATCH, triggert Store-Refresh → Liste rerendert.
+
+**Zutaten-Reihenfolge**: Erst nicht-abgehakt, dann abgehakt; innerhalb jeder Gruppe alphabetisch (`display_name COLLATE NOCASE`). Abgehakt = durchgestrichen + grauer Text.
+
+**Mengen-Formatierung** (`src/lib/quantity-format.ts`, neu):
+- `formatQuantity(q: number | null): string`
+- `null` → `''`
+- Ganz-nahe-Ganzzahl (Epsilon 0.01) → Integer
+- Sonst auf max. 2 Nachkommastellen, trailing Nullen weg
+- Beispiele: `400 → "400"`, `0.5 → "0.5"`, `0.333 → "0.33"`, `null → ""`
+
+**Aktionen im Footer**:
+- „Erledigte entfernen" — sichtbar wenn ≥ 1 Check, kein Confirm (reversibel genug)
+- „Liste leeren" — Confirm via `confirmAction`: „Komplette Einkaufsliste löschen? Das macht nicht rückgängig."
+
+**Empty State**: Icon `ShoppingCart` (große Version), „Einkaufswagen ist leer", Hint „Lege Rezepte auf der Wunschliste in den Wagen, um sie hier zu sehen."
+
+**Offline-Verhalten**: Wie die Wunschliste — alle Mutating-Calls via `requireOnline()`. Service-Worker cached nichts von `/api/shopping-list/*` (network-only analog zu Wishlist). Die PWA-Seite selbst wird vom SW-Shell-Cache serviert, aber ohne Daten. Offline-Robustheit (local queue + sync) ist **out of scope** für v1.
+
+## Testing
+
+### Unit/Integration-Tests (Vitest, in-memory DB)
+
+- `tests/integration/shopping-repository.test.ts`:
+  - `addRecipeToCart` idempotent, `ON CONFLICT` überschreibt `servings`
+  - Aggregation: gleiche `(name_key, unit_key)` summiert; unterschiedliche unit_keys bleiben getrennt
+  - Portions-Skalierung: `servings_default=4`, `servings=2` → alle Mengen halbiert
+  - Nulls: `quantity IS NULL` → `total_quantity IS NULL`; `unit IS NULL` → `unit_key=''`
+  - `toggleCheck` persistiert über `listShoppingList`-Aufrufe
+  - Abgehakt-Status überlebt Entfernen eines Rezepts, solange Schlüssel von einem anderen kommt
+  - `clearCheckedItems`: entfernt nur vollständig abgehakte Rezepte + räumt Orphan-Checks
+  - `countUncheckedItems` nach diversen Ops korrekt
+  - `clearCart` cleant beide Tabellen
+- `tests/unit/shopping-cart-store.test.ts`:
+  - Mock-Fetch, testet refresh-Trigger nach add/remove
+  - `isInCart(id)` reflektiert aktuellen Zustand
+  - `uncheckedCount` reactive nach refresh
+- `tests/unit/quantity-format.test.ts`:
+  - `formatQuantity(400) === "400"`
+  - `formatQuantity(0.5) === "0.5"`
+  - `formatQuantity(0.333333) === "0.33"`
+  - `formatQuantity(400.001) === "400"` (Epsilon)
+  - `formatQuantity(null) === ""`
+
+### E2E-Tests (Playwright, `tests/e2e/remote/shopping.spec.ts`)
+
+**Wichtig**: E2E-Tests laufen gegen `kochwas-dev.siegeln.net` und erfordern einen erfolgreichen Deploy des Features. Werden nach dem Feature-Merge manuell ausgelöst, nicht im Rahmen der Implementierungs-Phase.
+
+Abgedeckt:
+- Rezept auf Wunschliste → Cart-Button klicken → Header-Badge erscheint
+- Navigation zu `/shopping-list`, Portions-Stepper hoch/runter → Zutatenmengen reagieren
+- Zutat abhaken → Badge-Count sinkt, Zeile durchgestrichen, Reload persistiert
+- „Erledigte entfernen" → vollständig abgehakte Rezepte weg, teilweise abgehakte bleiben
+- „Liste leeren" → Empty-State, Badge verschwindet
+- Zwei Rezepte mit gleicher Zutat (Fixture-Setup) → aggregierte Zeile mit Summe
+- Cleanup-Fixture entfernt Cart + Checks nach jedem Test
+
+**Nicht getestet**: exakte CSS-Styles, Animationen — visuelle Kontrolle beim Deploy.
+
+## Implementierungs-Reihenfolge (Hinweis für Plan)
+
+1. Migration 013 + Repository + Unit-Tests
+2. API-Routen + Integrationstests
+3. Client-Store
+4. Header-Badge-Icon
+5. Wunschlisten-Karte Relayout + Cart-Button

+# Hauptseite: "Zuletzt angesehen" Sort + Collapsible Sections
+
+## Kontext
+
+Die Hauptseite (`src/routes/+page.svelte`) hat heute drei Sektionen — "Deine
+Favoriten", "Zuletzt hinzugefügt", "Alle Rezepte" — und vier Sort-Optionen
+für "Alle Rezepte" (Name, Bewertung, Zuletzt gekocht, Hinzugefügt). Der
+User möchte:
+
+1. Eine fünfte Sort-Option "Zuletzt angesehen" für "Alle Rezepte"
+2. "Deine Favoriten" und "Zuletzt hinzugefügt" auf-/zuklappbar machen
+
+Beides reduziert visuelle Last und gibt Zugriff auf "kürzlich
+beschäftigte mich" Rezepte ohne Suche.
+
+## Design-Entscheidungen (durch Brainstorming bestätigt)
+
+- **View-Tracking**: zählt sofort beim Laden der Detailseite — kein Threshold
+- **Storage**: SQLite, pro Profil (konsistent mit Ratings, Cooked, Wishlist)
+- **Collapsibles**: standardmäßig offen, User-Wahl persistiert pro Device
+
+## Sektion 1 — Schema & View-Tracking
+
+### Migration
+
+Neue Datei `src/lib/server/db/migrations/014_recipe_view.sql`
+(Numbering: aktuell ist die letzte Migration `013_shopping_list.sql`):
+
+```sql
+CREATE TABLE recipe_view (
+  profile_id INTEGER NOT NULL REFERENCES profiles(id) ON DELETE CASCADE,
+  recipe_id INTEGER NOT NULL REFERENCES recipes(id) ON DELETE CASCADE,
+  last_viewed_at TEXT NOT NULL DEFAULT (datetime('now')),
+  PRIMARY KEY (profile_id, recipe_id)
+);
+CREATE INDEX idx_recipe_view_recent
+  ON recipe_view(profile_id, last_viewed_at DESC);
+```
+
+Idempotent über `INSERT OR REPLACE` — mehrfache Visits ein- und desselben
+Profils auf dasselbe Rezept führen nur zur Aktualisierung des Timestamps,
+kein Multi-Insert.
+
+Cascade auf beide FKs: löscht ein User ein Rezept oder ein Profil, gehen
+zugehörige Views automatisch mit.
+
+### API
+
+Neuer Endpoint `POST /api/recipes/[id]/view`:
+
+```
+Request body: { "profile_id": number }
+Response: 204 No Content
+Errors:
+  - 400 wenn profile_id fehlt oder kein Number
+  - 404 wenn Recipe nicht existiert (FK-Violation)
+  - 404 wenn Profil nicht existiert (FK-Violation)
+```
+
+Implementation: einfache `INSERT OR REPLACE` mit den IDs. `last_viewed_at`
+nutzt den Default (`datetime('now')`).
+
+### Client-Hook
+
+In `src/routes/recipes/[id]/+page.svelte`, in `onMount`:
+
+```ts
+if (profileStore.active) {
+  void fetch(`/api/recipes/${recipe.id}/view`, {
+    method: 'POST',
+    headers: { 'content-type': 'application/json' },
+    body: JSON.stringify({ profile_id: profileStore.active.id })
+  });
+}
+```
+
+Fire-and-forget, kein UI-Block, kein Error-Handling — wenn der Beacon
+fehlschlägt, ist es kein User-Visible-Bug, das nächste View korrigiert
+es.
+
+## Sektion 2 — Sort "Zuletzt angesehen"
+
+### Page
+
+In `src/routes/+page.svelte`:
+
+```ts
+type AllSort = 'name' | 'rating' | 'cooked' | 'created' | 'viewed';
+const ALL_SORTS = [
+  ...,
+  { value: 'viewed', label: 'Zuletzt angesehen' }
+];
+```
+
+### API
+
+`GET /api/recipes/all` bekommt einen optionalen `profile_id`-Query-Param.
+Der Endpoint reicht ihn an `listAllRecipesPaginated` durch.
+
+### DB-Layer
+
+`listAllRecipesPaginated` in `src/lib/server/recipes/search-local.ts`
+bekommt einen optionalen `profileId: number | null`-Parameter. Wenn
+`sort === 'viewed'` UND `profileId !== null`:
+
+```sql
+SELECT r.*, ...
+FROM recipes r
+LEFT JOIN recipe_view v
+  ON v.recipe_id = r.id AND v.profile_id = :profileId
+ORDER BY v.last_viewed_at DESC NULLS LAST,
+         r.title COLLATE NOCASE ASC
+LIMIT :limit OFFSET :offset
+```
+
+Bei `sort === 'viewed'` ohne `profileId`: fällt auf alphabetische
+Sortierung zurück (kein Crash, sinnvolles Default-Verhalten).
+
+### Reactive Refetch bei Profile-Switch
+
+Auf Home-Page-Ebene: ein `$effect` der auf `profileStore.activeId` lauscht
+und — wenn `allSort === 'viewed'` — `setAllSort('viewed')` retriggert
+(forciert Refetch mit neuem profile_id). Sonst (anderer Sort) keine
+Aktion, weil andere Sorts nicht profilabhängig sind.
+
+### Snapshot-Kompatibilität
+
+Der existierende `rehydrateAll(sort, count, exhausted)` in `+page.svelte`
+muss `profile_id` mitschicken, sonst zeigt der Back-Nav für sort='viewed'
+einen anderen Inhalt als vor dem Forward-Klick. Das gleiche gilt für
+`loadAllMore` und `setAllSort`.
+
+## Sektion 3 — Auf-/Zuklappbare Sektionen
+
+### State
+
+In `src/routes/+page.svelte`:
+
+```ts
+type CollapseKey = 'favorites' | 'recent';
+let collapsed = $state<Record<CollapseKey, boolean>>({
+  favorites: false,
+  recent: false
+});
+
+const STORAGE_KEY = 'kochwas.collapsed.sections';
+
+function toggle(key: CollapseKey) {
+  collapsed[key] = !collapsed[key];
+  localStorage.setItem(STORAGE_KEY, JSON.stringify(collapsed));
+}
+```
+
+In `onMount`: aus localStorage parsen, fehlerhafte JSON ignorieren
+(default-state behalten).
+
+### Markup
+
+Pro Sektion:
+
+```svelte
+<section class="listing">
+  <button
+    class="section-head"
+    onclick={() => toggle('favorites')}
+    aria-expanded={!collapsed.favorites}
+  >
+    <ChevronDown size={18} class:rotated={collapsed.favorites} />
+    <h2>Deine Favoriten</h2>
+    <span class="count">{favorites.length}</span>
+  </button>
+  {#if !collapsed.favorites}
+    <div transition:slide={{ duration: 180 }}>
+      <ul class="cards">…</ul>
+    </div>
+  {/if}
+</section>
+```
+
+### Visual / CSS
+
+- Header `<button>`: transparenter Border, full-width, `display: flex`,
+  `align-items: center`, `gap: 0.5rem`, `min-height: 44px` (Tap-Target)
+- Chevron-Icon (lucide-svelte `ChevronDown`): rotiert auf
+  `transform: rotate(-90deg)` wenn `.rotated`
+- Count-Pill rechts: kleiner grauer Text, hilft zu sehen wie viel hinter
+  einer zugeklappten Sektion steckt
+- Hover: leichter Hintergrund (`#f4f8f5`, wie andere interaktive Elemente)
+- Animation: `svelte/transition`'s `slide`, ~180 ms
+
+### Persistenz-Format
+
+```json
+{ "favorites": false, "recent": true }
+```
+
+Truthy = collapsed. Default-Zustand wenn key fehlt: beide false.
+
+### "Alle Rezepte" bleibt nicht-collapsible
+
+Hauptliste, immer sichtbar — User würde das Scrollen verlieren.
+
+## Test-Strategie
+
+### Schema/Migration
+
+- Migrations-Test (existierendes Pattern in `tests/integration`): nach
+  `applyMigrations` muss `recipe_view` existieren mit erwarteten
+  Spalten
+
+### View-Endpoint
+
+- `POST /api/recipes/[id]/view` Integration-Test:
+  - Erstes POST → Row mit `last_viewed_at` ungefähr `now`
+  - Zweites POST → gleiche Row, `last_viewed_at` aktualisiert
+  - POST mit ungültiger profile_id → 404
+  - POST mit ungültiger recipe_id → 404
+  - POST ohne profile_id im Body → 400
+
+### Sort-Logik
+
+- Unit-Test für `listAllRecipesPaginated(db, 'viewed', limit, offset, profileId)`:
+  - Mit Views-Daten: angesehene Rezepte zuerst (DESC nach `last_viewed_at`),
+    Rest alphabetisch
+  - Ohne profileId: fallback auf alphabetisch
+  - Mit profileId aber ohne Views: alle als NULL → alphabetisch
+
+### Collapsibles (manuell oder unit)
+
+- localStorage-Persistenz: Toggle, Reload, gleicher State
+- Default-State wenn localStorage leer/corrupt: beide offen
+- Ein Unit-Test für eine reine Helper-Funktion (parse/serialize), Markup
+  ist Snapshot-mässig nicht so wertvoll testbar
+
+## Reihenfolge der Umsetzung
+
+1. Migration + DB-Layer + Sort-Query (`search-local.ts`-Erweiterung)
+2. View-Endpoint (`POST /api/recipes/[id]/view`) + Client-Beacon in
+   `recipes/[id]/+page.svelte`
+3. Sort-Option in `+page.svelte` UI + API-Param weiterreichen +
+   profile_id in `loadAllMore`/`rehydrateAll`/`setAllSort` durchreichen
+4. Collapsible-Pattern in `+page.svelte` für Favoriten und Recent
+
+Jede Phase atomar committen + pushen.
