+# Specifiche Tecniche: Integrazione Servizio `/miei` con PWA Canti
+
+Questo documento descrive le specifiche dell'endpoint `/miei` implementato sul server Node.js e fornisce le linee guida per implementare la sincronizzazione e l'invio delle playlist locali e dei canti personalizzati ("canti miei") dalla PWA.
+
+---
+
+## 🌐 Dettagli dell'Endpoint `/miei`
+
+- **Metodo HTTP**: `POST`
+- **URL di Sviluppo**: `http://localhost:3000/miei` (o l'IP/porta del tuo server in produzione)
+- **Content-Type**: `application/json`
+- **Limite Dimensione Body**: `10MB` (per supportare liste e testi completi di canti)
+
+### 🔑 Identificazione Utente (`uid`)
+L'endpoint richiede l'identificativo unico dell'utente (`uid`). Può essere trasmesso in tre modi (in ordine di priorità):
+1. **Header HTTP**: `x-user-uid` (scelta consigliata) o `uid`
+2. **Query Parameter**: `?uid=<user_uid>`
+3. **Wrapper nel Body**: Se il corpo è un oggetto del tipo `{ "uid": "...", "canti": [...] }`
+
+> [!WARNING]
+> L'UID dell'utente deve essere una stringa valida e sicura. Sono accettati solo caratteri alfanumerici, trattini e trattini bassi (`^[a-zA-Z0-9_\-]+$`). Qualsiasi tentativo di path traversal (es. contenente `.` o `/`) restituirà un errore `400 Bad Request`.
+
+---
+
+## 📦 Formato dei Dati Richiesto (Payload)
+
+L'endpoint si aspetta di ricevere un **array JSON** contenente la lista dei canti dell'utente (formato analogo a `canti.json`). 
+
+### Esempio di Payload (Array di Canti)
+```json
+[
+  {
+    "id_canti": 9001,
+    "titolo": "Mio Canto Personalizzato 1",
+    "momenti": ["Ingresso"],
+    "periodi": ["Lode"],
+    "testo": "Testo del mio canto personalizzato...\nRit: Alleluia!"
+  },
+  {
+    "id_canti": 9002,
+    "titolo": "Mio Canto Personalizzato 2",
+    "momenti": ["Comunione"],
+    "periodi": [],
+    "testo": "Testo del secondo canto..."
+  }
+]
+```
+
+---
+
+## 🔄 Comportamento del Server
+
+1. **Ricezione e Validazione**:
+   - Estrae l'UID ed il payload dei canti.
+   - Valida l'UID (sicurezza path traversal) e verifica che il payload sia un array JSON. In caso contrario, risponde con `400 Bad Request`.
+2. **Logica di Backup**:
+   - Se nella cartella `data/` del server esiste già un file associato all'utente (`data/<uid>.json`), ne crea automaticamente una copia di backup rinominandola o copiandola in `data/<uid>.bak.json`.
+3. **Salvataggio**:
+   - Scrive il nuovo JSON in `data/<uid>.json`.
+   - Risponde con `200 OK` e un JSON di conferma:
+     ```json
+     {
+       "success": true,
+       "message": "File salvato con successo.",
+       "uid": "utente_test_123",
+       "backupCreated": true
+     }
+     ```
+
+---
+
+## 🛠️ Requisiti per l'Implementazione nella PWA (Client Locale Mac M1)
+
+L'istanza di Antigravity che lavora sul codice della PWA locale dovrà implementare una funzione di sincronizzazione (es. `syncLocalDataToServer`) che esegua i seguenti passi:
+
+1. **Recupero dei dati locali**:
+   - Estrarre le playlist locali e i canti personalizzati creati dall'utente (solitamente salvati in `localStorage`, `IndexedDB`, o altro database locale).
+2. **Normalizzazione e Formattazione**:
+   - Formattare e unire queste informazioni in un unico array JSON strutturato con i campi chiave per ciascun canto (`id_canti`, `titolo`, `momenti`, `periodi`, `testo`).
+3. **Invio al Server**:
+   - Effettuare una chiamata `fetch` (POST) verso l'endpoint `/miei`.
+   - Passare l'UID dell'utente autenticato (es. da Firebase Auth o altro sistema di sessione) tramite l'header `x-user-uid`.
+4. **Gestione del Feedback**:
+   - Mostrare all'utente una notifica di successo o gestire eventuali errori di rete o validazione.

+# Piano di Implementazione: Importazione Playlist e Canti della Comunità
+
+Questo piano descrive i dettagli tecnici per l'aggiunta di una funzione che consente di importare localmente tutte le playlist e i canti personalizzati di una comunità attiva.
+
+## User Review Required
+
+> [!IMPORTANT]
+> L'importazione comporterà il salvataggio dei canti personalizzati della comunità direttamente nei "Miei Canti" dell'utente (evitando duplicati) e la creazione di playlist locali. Le playlist locali create includeranno:
+> 1. Una playlist principale con il nome della comunità stessa contenente tutti i canti della comunità con le rispettive tonalità, velocità di scorrimento e testi personalizzati/aggiuntivi.
+> 2. Tutte le singole scalette/playlist della comunità importate come playlist locali indipendenti e modificabili.
+
+## Proposed Changes
+
+### Servizi e Logica di Business
+
+#### [MODIFY] [playlist.service.ts](file:///Users/davidfrassi/SRC/agenti/canti/src/app/services/playlist.service.ts)
+Aggiungeremo un metodo helper o esporremo le funzioni di salvataggio di massa per le playlist importate, garantendo che le impostazioni dei brani (`songSettings` contenenti tonalità e velocità di scorrimento) siano preservate correttamente.
+
+### Pagina Impostazioni (Settings Page)
+
+#### [MODIFY] [settings.page.html](file:///Users/davidfrassi/SRC/agenti/canti/src/app/pages/settings/settings.page.html)
+Nel gruppo "Comunità", quando una comunità è attiva, aggiungeremo un nuovo pulsante sotto i dettagli della comunità:
+- **Pulsante**: "Importa Playlist e Canti" con icona `cloud-download-outline`.
+
+#### [MODIFY] [settings.page.ts](file:///Users/davidfrassi/SRC/agenti/canti/src/app/pages/settings/settings.page.ts)
+Implementeremo il metodo `importComunitaPlaylists()` che svolgerà i seguenti passaggi:
+1. **Verifica dello Stato**: Si assicura che una comunità sia attiva e che i dati siano caricati.
+2. **Importazione dei Canti Personalizzati**:
+   - Scorrerà i canti di `comunitaService.comunitaCantiPersonali()`.
+   - Per ciascun canto, verificherà se è già presente nei "Miei Canti" (tramite `myCantiService.myCanti()`).
+   - Se assente, lo aggiungerà con prefisso ID `my_` ed effettuerà il salvataggio in locale su `MyCantiService`.
+3. **Creazione della Playlist della Comunità**:
+   - Creerà una playlist avente come nome il nome della comunità stessa.
+   - Popolerà i canti associando sia i canti standard sia i canti personali importati.
+   - Assocerà le impostazioni di tonalità e velocità di scorrimento da `comunitaCantiSettings()`. Per la velocità, si utilizzerà la formula di conversione standard (es. `Math.round(speed / 100)`).
+4. **Importazione delle Scalette (Playlist) Aggiuntive**:
+   - Per ciascuna scaletta in `comunitaService.comunitaScalette()`, creerà una playlist locale corrispondente.
+   - Per ciascun canto della scaletta, cercherà se esiste un'impostazione in `comunitaCantiSettings()` per impostare tonalità e velocità specifiche all'interno della playlist.
+5. **Salvataggio e Feedback**:
+   - Salverà tutte le nuove playlist tramite `playlistService.savePlaylist()`.
+   - Mostrerà un alert di conferma iniziale e un toast di successo finale.
+
+## Verification Plan
+
+### Manual Verification
+- Attivare una comunità di prova (es. con codice noto o inserendone uno valido).
+- Andare nelle impostazioni e cliccare sul nuovo pulsante "Importa Playlist e Canti".
+- Verificare la comparsa dell'alert di conferma.
+- Confermare l'importazione.
+- Verificare tramite Toast e navigando nella home che:
+  - Sia presente una playlist locale con il nome della comunità contenente tutti i canti ordinati e configurati.
+  - Siano presenti le playlist secondarie della comunità convertite in playlist locali.
+  - Le tonalità modificate e le velocità di scorrimento siano state importate correttamente per ciascun canto all'interno delle playlist.
+  - I canti personali/aggiuntivi siano stati importati nella sezione "Miei Canti" e siano visualizzabili.

+# Piano delle Azioni per la Generazione di una Batteria di Test (`.spec.ts`)
+
+Questo documento descrive in dettaglio la strategia, l'analisi dello stato attuale e l'elenco delle azioni sequenziali necessarie per implementare una suite completa di test unitari e di integrazione per tutte le classi (servizi, pagine e componenti) dell'applicazione Angular/Ionic.
+
+---
+
+## 📊 Analisi dello Stato Attuale dei Test
+
+L'applicazione utilizza **Angular v20**, **Ionic v8**, e il framework di test standard **Jasmine** abbinato al test runner **Karma**. 
+
+Un'analisi del codice ha rilevato la seguente situazione per ciascun componente chiave:
+
+### 1. Servizi (`src/app/services`)
+I servizi gestiscono la logica di business fondamentale (audio, sincronizzazione, storage, stato).
+*   ❌ `audio-engine.service.ts` — **Nessun test**
+*   ❌ `canti-letture.service.ts` — **Nessun test**
+*   ❌ `canti.service.ts` — **Nessun test**
+*   ❌ `comunita.service.ts` — **Nessun test**
+*   ❌ `connectivity.service.ts` — **Nessun test**
+*   ❌ `lyrics-parser.service.ts` — **Nessun test**
+*   ❌ `media-session.service.ts` — **Nessun test**
+*   ⚠️ `my-canti.service.ts` — **Spec esistente ma corrotto/obsoleto** (`my-canti.spec.ts` fa riferimento a una classe `MyCanti` che non esiste, la classe reale è `MyCantiService`).
+*   ❌ `playlist.service.ts` — **Nessun test**
+*   ❌ `settings.service.ts` — **Nessun test**
+*   ❌ `stats.service.ts` — **Nessun test**
+*   ❌ `theme.service.ts` — **Nessun test**
+*   ❌ `youtube-player.service.ts` — **Nessun test**
+
+### 2. Pagine (`src/app/pages` & `src/app/home`)
+Le pagine gestiscono la visualizzazione e l'interazione con l'utente.
+*   ⚠️ `home.page.ts` — Spec esistente (`home.page.spec.ts`) ma limitato al boilerplate base (verifica solo la creazione).
+*   ⚠️ `display.page.ts` — Spec esistente (`display.page.spec.ts`) solo boilerplate base.
+*   ⚠️ `player.page.ts` — Spec esistente (`player.page.spec.ts`) solo boilerplate base.
+*   ❌ `playlist.page.ts` — **Nessun test**
+*   ⚠️ `propose-canto.page.ts` — Spec esistente (`propose-canto.page.spec.ts`) solo boilerplate base.
+*   ❌ `settings.page.ts` — **Nessun test**
+
+### 3. Componenti (`src/app/components`)
+*   ❌ `qr-scanner/qr-scanner.component.ts` — **Nessun test**
+
+---
+
+## 🛠️ Strategia di Mocking e Test in Angular/Ionic
+
+Per testare efficacemente queste classi in isolamento, definiremo una strategia di mocking standard:
+
+1.  **Storage di Ionic (`@ionic/storage-angular`)**:
+    Molti servizi (`MyCantiService`, `SettingsService`, `ComunitaService`) dipendono dallo Storage. Creeremo un mock per simulare i metodi `get`, `set` e `remove` usando una mappa in memoria.
+2.  **Controller di Ionic (`ToastController`, `ModalController`, `AlertController`)**:
+    Utilizzeremo `jasmine.createSpyObj` per simulare la creazione e la presentazione dei componenti UI di Ionic senza istanziarli realmente nel DOM durante i test dei servizi.
+3.  **Ambiente HTML5 (Audio, Window)**:
+    Servizi come `AudioEngineService` e `YoutubePlayerService` interagiscono con le API audio del browser e l'oggetto `window`. Useremo dei mock o spy su `Audio`, `window.location`, ecc.
+
+---
+
+## 🚀 Elenco Dettagliato delle Azioni da Compiere
+
+Le azioni sono suddivise in 6 fasi logiche per garantire un approccio sistematico e sicuro.
+
+### Fase 1: Verifica dell'Ambiente e Correzione dei Test Esistenti
+Prima di scrivere nuovi test, dobbiamo assicurarci che l'infrastruttura di test esistente sia stabile e funzionante.
+
+- [ ] **Azione 1.1: Esecuzione iniziale dei test**
+  * Eseguire `npm run test` (o `ng test --watch=false`) per verificare se la suite iniziale compila ed è verde.
+- [ ] **Azione 1.2: Correzione di `my-canti.spec.ts`**
+  * Rinominare il file in `my-canti.service.spec.ts` per uniformità.
+  * Correggere gli import: importare `MyCantiService` anziché `MyCanti`.
+  * Configurare il `TestBed` fornendo il mock per `Storage`, `CantiService` e `ToastController`.
+  * Verificare che il test passi con successo.
+- [ ] **Azione 1.3: Aggiornamento dei boilerplate delle pagine esistenti**
+  * Risolvere eventuali errori nei test pregenerati (`home.page.spec.ts`, `display.page.spec.ts`, `player.page.spec.ts`, `propose-canto.page.spec.ts`) fornendo i moduli minimi (`IonicModule`, `RouterTestingModule`) e i mock dei servizi iniettati nei loro costruttori.
+
+---
+
+### Fase 2: Implementazione dei Test sui Servizi (Core Logico)
+I servizi sono la priorità in quanto non hanno dipendenze grafiche complesse e contengono la logica di business principale.
+
+- [ ] **Azione 2.1: Test per `connectivity.service.ts` e `theme.service.ts`**
+  * *Perché:* Sono i più semplici e privi di dipendenze esterne pesanti.
+  * *Test:* Cambiamenti di stato della rete online/offline, applicazione corretta delle classi CSS per i temi (scuro/chiaro).
+- [ ] **Azione 2.2: Test per `lyrics-parser.service.ts`**
+  * *Casi di test:* Parsing corretto dei testi dei canti con accordi tra parentesi (es. `[Do]`), gestione delle righe vuote, estrazione del testo pulito, formattazione.
+- [ ] **Azione 2.3: Test per `settings.service.ts`**
+  * *Casi di test:* Caricamento delle impostazioni di default da storage, salvataggio di nuove impostazioni, gestione del cambio di dimensione del testo, export/import delle impostazioni.
+- [ ] **Azione 2.4: Test per `stats.service.ts`**
+  * *Casi di test:* Incremento delle statistiche di visualizzazione di un canto, persistenza su storage, generazione dei report dei canti più cantati.
+- [ ] **Azione 2.5: Test per `canti.service.ts` e `canti-letture.service.ts`**
+  * *Casi di test:* Lettura del database dei canti, filtri di ricerca per titolo/testo/momento liturgico, associazione tra letture del giorno e canti consigliati (sulla base delle strategie liturgiche descritte in `liturgia_strategy.md`).
+- [ ] **Azione 2.6: Test per `comunita.service.ts`**
+  * *Casi di test:* Gestione del codice comunità, sincronizzazione dei canti della comunità tramite chiamate HTTP (mocking di `HttpClient`), salvataggio in storage locale.
+- [ ] **Azione 2.7: Test per `playlist.service.ts`**
+  * *Casi di test:* Creazione, modifica e cancellazione di playlist, riordino dei canti all'interno di una playlist, salvataggio e ripristino da storage.
+- [ ] **Azione 2.8: Test per `media-session.service.ts`**
+  * *Casi di test:* Integrazione con l'API `navigator.mediaSession` del browser, aggiornamento dei metadati audio (titolo, autore, copertina), gestione degli eventi di riproduzione/pausa del sistema operativo.
+- [ ] **Azione 2.9: Test per `audio-engine.service.ts` e `youtube-player.service.ts`**
+  * *Casi di test:* Avvio, pausa, stop e seek delle tracce audio locali e dei video YouTube, gestione degli eventi di fine riproduzione, aggiornamento dello stato tramite Signals/RxJS.
+
+---
+
+### Fase 3: Implementazione dei Test sui Componenti Condivisi
+- [ ] **Azione 3.1: Test per `qr-scanner.component.ts`**
+  * *Casi di test:* Inizializzazione della fotocamera, gestione dei permessi negati, decodifica del codice QR (simulando l'evento del decoder), emissione del codice scansionato tramite `@Output()`, interruzione dello streaming video alla distruzione del componente.
+
+---
+
+### Fase 4: Implementazione e Arricchimento dei Test sulle Pagine (UI & Controller)
+Qui testeremo l'integrazione tra i servizi (mockati) e l'interfaccia utente di Ionic.
+
+- [ ] **Azione 4.1: Test approfonditi per `home.page.ts`**
+  * *Casi di test:* Visualizzazione dell'elenco dei canti, funzionamento della barra di ricerca (filtro istantaneo), apertura dei dettagli del canto, gestione della navigazione verso le altre pagine.
+- [ ] **Azione 4.2: Test approfonditi per `player.page.ts`**
+  * *Casi di test:* Interazione con i pulsanti di play/pause, scorrimento del testo a tempo, trasposizione degli accordi (es. +1 semitono, -1 semitono) con aggiornamento dinamico del testo a schermo.
+- [ ] **Azione 4.3: Test approfonditi per `display.page.ts`**
+  * *Casi di test:* Rendering corretto del testo del canto, applicazione del tema visivo e della dimensione del font dalle impostazioni, gestione del blocco dello spegnimento dello schermo (se implementato).
+- [ ] **Azione 4.4: Creazione e test per `playlist.page.ts`**
+  * *Casi di test:* Visualizzazione dell'elenco delle playlist dell'utente, creazione di una nuova playlist tramite popup, aggiunta di canti, eliminazione di canti con swipe.
+- [ ] **Azione 4.5: Test approfonditi per `propose-canto.page.ts`**
+  * *Casi di test:* Validazione del form di proposta (titolo obbligatorio, testo minimo), generazione della mailto URL corretta con il body in formato JSON, comportamento del pulsante di invio.
+- [ ] **Azione 4.6: Creazione e test per `settings.page.ts`**
+  * *Casi di test:* Toggle del tema scuro (con verifica dell'applicazione al DOM), selezione della dimensione del font, reset dei dati locali con richiesta di conferma tramite `AlertController`.
+
+---
+
+### Fase 5: Raccolta delle Metriche di Coverage e Rifinitura
+- [ ] **Azione 5.1: Configurazione del report di coverage**
+  * Assicurarsi che `karma.conf.js` sia configurato per esportare i dati in formato `lcov` o `html` (tramite `karma-coverage`).
+- [ ] **Azione 5.2: Generazione del report**
+  * Eseguire `ng test --code-coverage --watch=false`.
+  * Esaminare la cartella `coverage/` generata per individuare eventuali rami logici (branches) o righe non coperte nei servizi core.
+- [ ] **Azione 5.3: Incremento mirato del coverage**
+  * Aggiungere test specifici per coprire i casi limite (*edge cases*) e la gestione degli errori (es. fallimento delle chiamate HTTP, storage corrotto).
+
+---
+
+### Fase 6: Automazione in CI/CD (Opzionale ma Consigliato)
+- [ ] **Azione 6.1: Configurazione test headless**
+  * Configurare Karma per eseguire i test in modalità headless usando `ChromeHeadless` su sistemi di Continuous Integration (es. GitHub Actions).
+  * Aggiungere uno script npm `test:ci`: `"test:ci": "ng test --watch=false --browsers=ChromeHeadless"`.

+
+> [!TIP]
+> **Consiglio per l'efficienza**: Si raccomanda di iniziare ad implementare i test partendo dai servizi a più basso livello (come `ConnectivityService`, `ThemeService`, `LyricsParserService`) perché sono privi di dipendenze e consentono di stabilire rapidamente dei pattern di test solidi prima di affrontare servizi più complessi o interfacce grafiche.

+# Strategia SEO e Indicizzazione per la PWA dei Canti
+
+Questo documento definisce la strategia tecnica per consentire l'indicizzazione dei testi dei canti da parte dei motori di ricerca (in particolare Googlebot) e la corretta generazione delle anteprime (social cards) su piattaforme di messaggistica e social media (WhatsApp, Telegram, Facebook, ecc.), mantenendo intatta l'architettura PWA (Progressive Web App) offline-ready.
+
+---
+
+## 1. Il Contesto Tecnologico
+L'applicazione è sviluppata con:
+- **Angular 20** (Framework Core)
+- **Ionic 8** (UI & Routing integration)
+- **Angular Service Worker (`@angular/service-worker`)** per le funzionalità offline della PWA.
+
+---
+
+## 2. La Strategia Selezionata: Prerendering / Static Site Generation (SSG)
+
+Dato che i testi dei canti sono **dati statici** (non cambiano in base all'utente connesso e variano molto raramente), la soluzione ottimale è la **Static Site Generation (SSG)**, nota anche come **Prerendering**.
+
+### Come Funziona la Sinergia SSG + PWA
+1. **Fase di Build:** Durante la compilazione dell'app (`ng build`), Angular genera un file `index.html` statico e pre-renderizzato per ogni singolo canto (es. `/canti/tu-sei-sorgente/index.html`).
+2. **Scansione dello Spider (SEO):** Quando Googlebot o i crawler dei social richiedono l'URL di un canto, il server o la CDN distribuiscono immediatamente il file HTML statico già popolato con il testo del canto e con i meta tag corretti.
+3. **Idratazione e PWA (Client):** Quando un utente apre la pagina sul browser, Angular scarica i bundle JavaScript ed esegue l'**hydration** in background. L'applicazione "prende vita" come Single Page Application (SPA), attiva il Service Worker e abilita la navigazione offline e l'installabilità come PWA.
+
+---
+
+## 3. Fasi e Dettagli di Implementazione
+
+### Fase 1: Struttura degli URL e Routing Semantico
+Per facilitare la SEO, gli URL devono essere parlanti e privi di simboli di hash (`#`). Attualmente, l'applicazione utilizza già il routing basato su percorsi standard (PathLocationStrategy) in [app-routing.module.ts](file:///Users/davidfrassi/SRC/agenti/canti/src/app/app-routing.module.ts).
+
+È necessario definire una rotta dedicata per i singoli canti che accetti un parametro semantico (detto *slug* o *alias*), ad esempio:
+
+```typescript
+// src/app/app-routing.module.ts
+const routes: Routes = [
+  // ... altre rotte
+  {
+    path: 'canti/:slug',
+    loadChildren: () => import('./pages/canto-detail/canto-detail.module').then(m => m.CantoDetailPageModule)
+  }
+];
+```
+
+I collegamenti all'interno dell'applicazione per navigare verso i canti devono utilizzare il tag semantico `<a>` con la direttiva `routerLink`, per consentire a Googlebot di scoprire autonomamente tutte le pagine:
+
+```html
+<!-- EVITARE: pulsanti generici con eventi click gestiti in JS -->
+<ion-item (click)="navigaAlCanto(canto.slug)">...</ion-item>
+
+<!-- CONSIGLIATO: vero tag link HTML -->
+<a [routerLink]="['/canti', canto.slug]" class="canto-link">
+  <ion-label>{{ canto.titolo }}</ion-label>
+</a>
+```
+
+---
+
+### Fase 2: Gestione dei Meta Tag Dinamici
+Ogni canto deve avere un titolo e una descrizione univoci e ottimizzati per la SEO. In Angular si utilizzano i servizi `Title` e `Meta` di `@angular/platform-browser` per aggiornare i metadati all'inizializzazione del componente:
+
+```typescript
+// src/app/pages/canto-detail/canto-detail.page.ts

+
+### Fase 3: Configurazione del Prerendering (SSG) in Angular 20
+In Angular 20, l'abilitazione del server-side rendering e del prerendering statico durante la compilazione avviene aggiungendo il pacchetto SSR ufficiale:
+
+```bash
+ng add @angular/ssr
+```
+
+Questo comando configura automaticamente l'applicazione modificando `angular.json` e creando i file necessari per la compilazione lato server.
+
+#### Configurazione delle rotte da pre-renderizzare
+Poiché l'elenco dei canti è dinamico (es. risiede in file JSON o database), dobbiamo indicare ad Angular quali rotte generare staticamente durante il comando `ng build`.
+
+Si crea un file di configurazione per definire le rotte o si utilizza uno script per estrarle dinamicamente:
+
+1. **Creare un file delle rotte statiche** `prerender-routes.txt`:
+   ```txt
+   /home
+   /settings
+   /canti/tu-sei-sorgente
+   /canti/re-dei-re
+   /canti/lodi-al-altissimo
+   ```
+2. **Automatizzare la generazione di questo file** inserendo uno script (es. `generate-routes.js`) da eseguire prima della build che legge l'elenco dei canti dal file JSON locale e scrive l'elenco dei percorsi in `prerender-routes.txt`.
+3. **Configurare `angular.json`** per consumare questo file:
+   ```json
+   "prerender": {
+     "discoverRoutes": false,
+     "routesFile": "prerender-routes.txt"
+   }
+```
+
+Al termine della build (`npm run build`), nella cartella di distribuzione (es. `dist/canticristiani/browser`) verranno generate cartelle fisiche con i file `index.html` pronti all'uso per ciascuna rotta definita.
+
+---
+
+### Fase 4: Sitemap.xml e Robots.txt
+Per garantire che Googlebot trovi tempestivamente tutti i canti, è fondamentale generare un file `sitemap.xml` da posizionare nella radice del server web.
+
+#### Esempio di `sitemap.xml`:
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
+  <url>
+    <loc>https://canti.cristiani.it/home</loc>
+    <changefreq>weekly</changefreq>
+    <priority>1.0</priority>
+  </url>
+  <!-- Generato dinamicamente per ogni canto -->
+  <url>
+    <loc>https://canti.cristiani.it/canti/tu-sei-sorgente</loc>
+    <changefreq>monthly</changefreq>
+    <priority>0.8</priority>
+  </url>
+</urlset>
+```
+
+#### Esempio di `robots.txt`:
+```txt
+User-agent: *
+Allow: /
+
+Sitemap: https://canti.cristiani.it/sitemap.xml
+```
+
+---
+
+## 4. Vantaggi e Risultati Attesi
+- **Indicizzazione immediata:** Googlebot indicizzerà i testi dei canti all'istante, consentendo agli utenti di trovare la PWA cercando frammenti di testo o il titolo del canto direttamente su Google.
+- **Anteprime nei Social Perfette:** La condivisione dei link sui canali di comunicazione mostrerà anteprime ricche (titolo corretto, frammento del testo del canto e logo dell'app).
+- **Integrità PWA:** L'utente beneficerà di un caricamento iniziale ultra-veloce (grazie all'HTML pre-renderizzato) seguito dall'installazione offline e dall'esperienza fluida tipica dell'applicazione mobile.
