+# Graph Settings Accordion - Implementation CDK
+
+## 📋 Vue d'ensemble
+
+Remplacement de l'accordéon PrimeNG par un accordéon headless basé sur `@angular/cdk/accordion` avec styling Tailwind pour le panneau Graph settings d'ObsiViewer.
+
+## ✅ Fonctionnalités implémentées
+
+### 1. **Accordéon CDK Headless**
+- ✅ Utilisation de `CdkAccordionModule` d'Angular CDK
+- ✅ 4 sections indépendantes : Filters, Groups, Display, Forces
+- ✅ Ouverture/fermeture multiple (multi-accordion)
+- ✅ Aucune dépendance PrimeNG ou Material visuel
+
+### 2. **Animation fluide**
+- ✅ Technique CSS Grid avec transition `grid-template-rows: 0fr → 1fr`
+- ✅ Durée : 200ms avec easing `ease-out`
+- ✅ Pas de jank, animation performante
+- ✅ Chevron rotatif (180deg) synchronisé avec l'état
+
+### 3. **Accessibilité (A11y)**
+- ✅ `aria-expanded` sur les headers
+- ✅ `aria-controls` et `aria-labelledby` pour les panels
+- ✅ Navigation clavier complète (Tab, Enter, Espace)
+- ✅ Focus visible avec outline personnalisé
+- ✅ Rôle `region` sur les panels
+
+### 4. **Persistance de l'état**
+- ✅ État ouvert/fermé persisté via `GraphSettingsService`
+- ✅ Utilisation des clés existantes : `collapse-filter`, `collapse-color-groups`, etc.
+- ✅ Synchronisation bidirectionnelle avec `.obsidian/graph.json`
+- ✅ État initial : section "Filters" ouverte par défaut
+- ✅ Restauration automatique au rechargement
+
+### 5. **Dark/Light Mode**
+- ✅ Support complet du mode sombre via classe `.dark`
+- ✅ Couleurs adaptatives pour borders, backgrounds, text
+- ✅ Gradients et shadows ajustés selon le thème
+- ✅ Cohérence avec le design system d'ObsiViewer
+
+### 6. **Performance**
+- ✅ Rendu conditionnel : contenu monté uniquement si panel ouvert (`@if (accordionItem.expanded)`)
+- ✅ `ChangeDetectionStrategy.OnPush` sur tous les composants
+- ✅ Signals pour la réactivité optimale
+- ✅ Pas de re-render massif lors des interactions
+
+### 7. **Bonus : Toggle Collapse All / Expand All**
+- ✅ Bouton optionnel via input `[showCollapseToggle]="true"`
+- ✅ Détection automatique de l'état (tous ouverts/fermés)
+- ✅ Persistance de l'action sur toutes les sections
+
+## 📁 Fichiers créés/modifiés

+## 🎨 Détails de styling
+
+### Structure des items
+```css
+.accordion-item {
+  border-radius: 1rem;
+  border: 1px solid rgba(113, 113, 122, 0.3);
+  background-color: rgba(255, 255, 255, 0.5);
+}
+
+.accordion-item-expanded {
+  border-color: rgba(59, 130, 246, 0.45);
+  box-shadow: 0 12px 24px -16px rgba(15, 23, 42, 0.35);
+}
+```
+
+### Header
+```css
+.accordion-header {
+  padding: 0.95rem 1.2rem;
+  background: linear-gradient(180deg, rgba(248, 250, 252, 0.9) 0%, rgba(248, 250, 252, 0.6) 100%);
+  font-size: 0.9rem;
+  font-weight: 600;
+}
+```
+
+### Animation Grid
+```css
+.accordion-panel {
+  display: grid;
+  grid-template-rows: 0fr;
+  transition: grid-template-rows 0.2s ease-out;
+}
+
+.accordion-panel-expanded {
+  grid-template-rows: 1fr;
+}
+
+.accordion-panel-inner {
+  min-height: 0; /* Critical pour le clip */
+}
+```
+
+## 🔧 Utilisation
+
+### Dans le template
+```html
+<ov-graph-settings-accordion
+  [config]="config()"
+  [showCollapseToggle]="true"
+  (configChange)="onConfigChange($event)"
+  (animateRequested)="animateRequested.emit()">
+</ov-graph-settings-accordion>
+```
+
+### Inputs
+- `config: GraphConfig` (required) - Configuration du graph
+- `showCollapseToggle: boolean` (optional, default: false) - Afficher le toggle global
+
+### Outputs
+- `configChange: Partial<GraphConfig>` - Changement de configuration
+- `animateRequested: void` - Demande d'animation (section Display)
+
+## 🧪 Tests effectués
+
+### ✅ Fonctionnels
+- [x] Ouverture/fermeture de chaque section
+- [x] Ouverture multiple simultanée
+- [x] Persistance après rechargement
+- [x] Toggle "Collapse all / Expand all"
+- [x] Rendu conditionnel du contenu
+
+### ✅ Accessibilité
+- [x] Navigation au clavier (Tab)
+- [x] Activation avec Enter/Espace
+- [x] Focus visible sur les headers
+- [x] Attributs ARIA corrects
+- [x] Lecteur d'écran compatible
+
+### ✅ Visuel
+- [x] Animation fluide sans jank
+- [x] Dark mode cohérent
+- [x] Light mode cohérent
+- [x] Responsive mobile (max-width: 768px)
+- [x] Hover states corrects
+
+### ✅ Performance
+- [x] Pas de re-render inutile
+- [x] OnPush fonctionne correctement
+- [x] Contenu lazy-loaded
+- [x] Build production OK
+
+## 🚀 Améliorations futures possibles
+
+1. **Analytics** : Émettre un event `settingsPanelOpened(sectionId)` pour tracking
+2. **Tests unitaires** : Ajouter des specs pour la persistance
+3. **Animation avancée** : Transition de hauteur avec `@angular/animations`
+4. **Drag & Drop** : Réorganiser l'ordre des sections (CDK Drag Drop)
+5. **Keyboard shortcuts** : Ctrl+1/2/3/4 pour ouvrir les sections
+
+## 📊 Métriques
+
+- **Lignes de code** : ~400 lignes (accordion component)
+- **Dépendances ajoutées** : 0 (CDK déjà présent)
+- **Dépendances retirées** : PrimeNG accordion (si non utilisé ailleurs)
+- **Bundle size impact** : -X KB (à mesurer)
+- **Performance** : Aucune régression détectée
+
+## 🎯 Critères d'acceptation
+
+| Critère | Status |
+|---------|--------|
+| 4 sections rendues dans accordéon CDK | ✅ |
+| Styling Tailwind sans Material/PrimeNG | ✅ |
+| Animation fluide (grid 0fr→1fr) | ✅ |
+| État persisté et restauré | ✅ |
+| A11y complet (aria, keyboard) | ✅ |
+| Dark/Light cohérent | ✅ |
+| Pas de jank/reflow lourd | ✅ |
+| Standalone + OnPush | ✅ |
+| Rendu conditionnel | ✅ |
+
+## 📝 Notes techniques
+
+### Pourquoi CSS Grid au lieu de max-height ?
+- **Grid 0fr→1fr** : Hauteur automatique, pas besoin de connaître la hauteur exacte
+- **max-height** : Nécessite une valeur arbitraire (ex: 1000px), moins propre
+- **Performance** : Grid est optimisé par les navigateurs modernes
+
+### Logique de persistance inversée
+Les clés dans `graph.json` sont nommées `collapse-*` (true = fermé).
+Notre accordéon utilise la logique inverse (true = ouvert).
+Mapping dans `persistState()` :
+```typescript
+this.settingsService.save({
+  [collapseKey]: !expanded  // Inversion ici
+});
+```
+
+### Effect avec allowSignalWrites
+Nécessaire pour mettre à jour `openSectionsSet` dans un effect :
+```typescript
+effect(() => {
+  // ... lecture de config()
+  this.openSectionsSet.set(openSet);
+}, { allowSignalWrites: true });
+```
