version update

Describes the estimate signature + TeX/PDF generation release impact:
signature pad on validation, role-aware accept/reject with signatures,
ProAccepted/ClientAccepted split, estimate.tex/estimate.pdf endpoints
in Yavsc.Api, vector TikZ signatures, PostIt PDF/TeX download buttons,
list refresh + title renames, the lualatex stdin runtime, and the
Emergency stop / log-write / RenderViewToString / Layout fixes.

 # Changelog
 
-## [1.0.8-rc25] - unstable
-
-### Added
-
-* [Yavsc.Api] Notification du performer à la création d'un rendez-vous
-  depuis PostIt, selon ses préférences de contact, sans supprimer l'envoi Org.
-* [Yavsc.Api][Yavsc.Server] Notification du performer à la signature
-  client d'un devis (JSON ou image), enregistrée pour l'accueil PostIt
-  et transmise par e-mail et SignalR.
-* [Yavsc.Api] Nouveau point d'entrée `GET /api/v1/notifications/me`
-  pour exposer les notifications publiques et ciblées à PostIt sur la
-  Home page ; les notifications d'administration restent filtrées.
-* [PostIt] Affichage des notifications sur la page d'accueil, avec
-  actualisation, indicateur de chargement et message d'erreur. Les
-  notifications publiques sont accessibles sans connexion et la liste
-  est rechargée lors d'un changement de session.
-
-### Changed
-
-* [PostIt] Insertion des liens de fichiers dès leur ajout au brouillon ;
-  les liens provisoires des nouveaux billets sont résolus au premier
-  enregistrement. Save conserve l'édition ouverte et est mis en valeur
-  lorsque le titre, le corps ou les pièces jointes sont modifiés.
-
-* [Projet] Instructions Copilot persistantes : mise à jour du changelog
-  par défaut à chaque commit, avec justification explicite des exceptions.
-
-### Fixed
-
-* [PostIt.Tests] Les tests du bandeau de session utilisent le bandeau
-  réellement monté dans la fenêtre headless, au lieu d'un contrôle détaché.
-  Les fenêtres sont fermées après chaque test et les quatre boutons
-  de navigation sont vérifiés.
-
-* [PostIt] Les liens Markdown des pièces jointes utilisent désormais
-  le même filtre de nom que l'upload serveur, avant l'encodage URL.
-  Le libellé conserve le nom original, notamment ses accents.
-
-* [Yavsc.Abstract][Yavsc.Blogs] Encodage des caractères non supportés
-  dans les noms de fichiers téléversés avec `_` au lieu de `#`, pour
-  éviter les fragments d'URL et permettre le téléchargement via les
-  fichiers statiques, notamment pour les noms accentués.
-
-* [Yavsc.Api][Yavsc.Blogs] Les appels API et la bande passante sont
-  désormais enregistrés côté serveur pour les requêtes authentifiées :
-  le middleware de télémétrie est maintenant branché après
-  l'authentification, ce qui permet de comptabiliser `ApiCalls` et
-  `BandwidthMb` au lieu d'enregistrer des zéros.
-
-## [1.0.8-rc24] - unstable
-
-### Added
-
-* [PostIt] Reconnection automatique aux salons de discussion au reconnect
-
-### Changed
-
-* [PostIt] La liste des billets et l'éditeur Markdown se partagent
-  l'espace disponible et défilent séparément ; un séparateur permet
-  de redimensionner les deux zones.
-
-### Fixed
-
-* [PostIt] Défilement des articles longs en édition et en aperçu :
-  suppression de la limite de hauteur qui masquait le contenu Markdown
-  et du défilement imbriqué autour d'AvaloniaEdit. Six tests headless
-  couvrent les barres automatiques, le redimensionnement et le
-  défilement indépendant de la liste.
-
-## [1.0.8-rc23] - unstable
-
-### Added
-
-* [PostIt] Badge « Publié » à côté du titre des billets publiés dans la
-  liste, mis à jour lors de la publication ou du retour en brouillon.
-* [PostIt] Gestion native du compte inspirée de `/Manage` : modification
-  du nom d'utilisateur, du nom complet et de l'adresse, téléversement
-  d'avatar, confirmation e-mail, préférence de courriel mensuel,
-  création ou changement de mot de passe et activation/désactivation
-  de l'authentification à deux facteurs.
-* [PostIt][Yavsc.Api] Sélection d'un agenda Google, gestion séparée des
-  comptes bancaires, dissociation des connexions externes et suppression
-  du compte avec confirmation du nom d'utilisateur.
-* [PostIt] Configuration du profil professionnel et des activités,
-  navigation vers les cercles et les publications depuis le compte.
-* [PostIt][Yavsc.Api] Administration des utilisateurs avec recherche
-  dans les métadonnées du profil et consultation de la consommation
-  de ressources.
-* [Yavsc.Server][Yavsc.Api][Yavsc.Blogs] Suivi de la consommation de
-  ressources, API de synthèse et migration `ResourceUsageRecords`.
-* [Tests] Couverture des parcours profil et professionnel, de l'API de
-  consommation de ressources et du renouvellement des jetons :
-  rotation à usage unique, appels simultanés, réponses 401 concurrentes
-  et rejet d'un jeton de renouvellement révoqué.
-
-### Changed
-
-* [PostIt] Réorganisation de la page de compte en sections de profil,
-  sécurité et préférences ; actions de modification désactivées tant
-  que le profil n'est pas chargé ou qu'une opération est en cours.
-* [PostIt] Utilisation de `PlaceholderText` à la place de `Watermark`
-  dans les pages de profil et de configuration professionnelle.
-* [Yavsc.Api] `GET account/me` renvoie le DTO partagé attendu par
-  PostIt, avec l'état de sécurité, les connexions externes, les comptes
-  bancaires et les compteurs du compte.
-
-### Fixed
-
-* [Yavsc.Api] Enregistrement des services ASP.NET Identity et des stores
-  EF nécessaires à `UserManager<ApplicationUser>` : leur absence
-  empêchait l'activation du contrôleur de compte et provoquait une 500.
-* [Yavsc.Api] Chargement du profil : réponse adaptée lorsqu'un jeton
-  ne contient pas d'identifiant utilisateur ou que le compte n'existe
-  plus, au lieu d'une exception serveur.
-* [PostIt] Synchronisation de tous les chemins de renouvellement des
-  jetons, y compris après une 401 et au démarrage : les appels
-  concurrents ne réutilisent plus le même `refresh_token`. Un rejet
-  `invalid_grant` efface la session et invite à se reconnecter.
-* [PostIt] Effacement des informations obsolètes après un échec de
-  rechargement du profil et normalisation des valeurs de calendrier
-  lors de la sauvegarde.
-* [PostIt][Yavsc.Api] Préservation de l'identité du profil professionnel
-  lors de son enregistrement.
-* [Yavsc.Api] Les coordonnées bancaires ne sont plus modifiées à partir
-  d'un résumé agrégé : opérations dédiées avec contrôle de propriété
-  et validation de longueur des champs.
-
-### Known limitations
-
-* [PostIt] L'ajout d'un nouveau fournisseur OAuth et la gestion des
-  crédits ne sont pas encore disponibles dans l'interface native.
-
-## [1.0.8-rc22] - unstable
-
-### Fixed
-
-User experience login into PostIt
-
-## [1.0.8-rc21] - unstable
-
-### Fixed
-
-User experience editing the blog article.
-
-## [1.0.8-rc20] - unstable
-
-Chat SignalR fonctionnel de bout en bout (connexion, salons multiples,
-envoi/réception de messages), enregistreur audio et localisation dans
-PostIt, intégration Live.Avalonia démarrée, et reverse-proxy nginx
-apprêté pour WebSocket.
-
-### Added
-
-* [PostIt] Interface de chat : page `ChatPage` (connexion au hub,
-  saisie du nom de salon, liste des messages et des membres présents),
-  entrée depuis la page d'accueil.
-* [PostIt] Envoi de messages dans un salon joint : DTO `ChatMessage`
-  (Name/Room/Message) pour l'événement `ReceiveMessage`, saisie avec
-  envoi sur `Enter`, commande inactive tant qu'aucune salle n'est en
-  focus (le hub refuse l'envoi hors salon, `LabNoJoinNoSend`).
-* [PostIt] Modèle multi-salles côté client : `JoinedRooms`,
-  `SelectedRoom` (salle en focus), messages et utilisateurs indexés par
-  salle (`FocusedMessages`/`FocusedUsers`), ComboBox de choix de la
-  salle active ; un `Join` sur une salle déjà jointe ne fait que
-  changer le focus.
-* [PostIt] Enregistreur audio (`AudioRecorder`, interface
-  `IPCMProcessor`) et ressources de localisation
-  (`Resources.{resx,en-EN,pt-PT}`).
-* [PostIt][WIP] Début d'intégration Live.Avalonia (preview XAML à
-  chaud ; encore KO).
-* [contrib] Bloc `location /chathub` dans `template.vhost` : upgrade
-  WebSocket (`Upgrade`/`Connection`), `proxy_read_timeout 3600s` et
-  `proxy_buffering off` — sans quoi la connexion SignalR tombait au
-  premier silence ou l'upgrade échouait derrière nginx.
-
-### Changed
-
-* [PostIt] `StatusNotice` déplacé de `Models` vers `ViewModels` et
-  enrichi d'une commande d'action optionnelle (`CheckCommand` +
-  `CheckCommandLabel`, interface `IWithLabel`) : le bandeau de statut
-  propose désormais l'action contextuelle (Connecter / Déconnecter /
-  Reconnecter / Vérifier la connexion).
-* [PostIt] `ChatViewModel` suit le cycle de vie complet de la
-  connexion : handlers `Reconnecting` / `Reconnected` / `Closed` de
-  `WithAutomaticReconnect`, pour refléter l'état réel au lieu d'un
-  `IsConnected` optimiste.
-* [Yavsc.Api] `AddSignalR().AddJsonProtocol(IncludeFields = true)` :
-  `ChatRoomInfo` n'expose que des champs publics, que System.Text.Json
-  ne sérialise pas par défaut — le client recevait des objets vides
-  (`Name` null, `Users` vide) et la liste des salons joints n'était
-  jamais alimentée.
-* [Yavsc.Server] `IConnexionManager.OnConnected` prend le `userName`
-  en paramètre (résolu depuis les claims dans `ChatHub`) au lieu de le
-  relire depuis un dictionnaire jamais alimenté.
-* [PostIt.Android] `network_security_config.xml` déplacé sous
-  `Resources/xml/` (chemin canonique Android).
-
-### Fixed
-
-* [Yavsc.Server] `KeyNotFoundException` dans
-  `HubConnectionManager.OnConnected` à chaque connexion SignalR :
-  `ChatUserNames` (et `ChatCxIds`) n'étaient jamais alimentés — relique
-  d'un `SetUserName` disparu lors d'une refactorisation. L'exception
-  dans `OnConnectedAsync` faisait fermer la connexion par le hub, et
-  PostIt affichait « Déconnecté (The server closed the connection…) »
-  immédiatement après la connexion.
-* [PostIt] URL du hub SignalR : retrait du préfixe `/api/v1` de
-  `ApiUrl` avant d'apposer `Constants.ChatHubPath` (le hub est mappé à
-  la racine du service, pas sous le préfixe versionné).
-* [PostIt] La `StatusBar` de la page chat référençait `Grid.Row="4"`
-  sur une grille à 3 rangées (rangée hors limites, bandeau invisible).
-
-## [1.0.8-rc19] - unstable
-
-[PostIt] Blogs UX
-
-### Fixed
-
-La saisie du billet est maintenant plutôt possible,
-en petit écran.
-
-## [1.0.8-rc18] - unstable
-
-* [PostIt] Page "About" avec lines vers le dépôt et les issues Forgejo
-
-* Accès aux fichiers personnels PostIt rendu fonctionnel de bout en bout
-(arbre de stockage indexé par le login, pas par le `sub`), boutons
-d'action des listes réparés (binding `$parent`), revendication `name`
-enfin présente dans les access tokens (branchement du `ProfileService`),
-et négociation HTTP/3 côté client PostIt.
-
-
-### Added
-
-* [PostIt] Négociation HTTP/3 (QUIC) pour les appels API Yavsc :
-  `DefaultRequestVersion = 3.0`, `DefaultVersionPolicy =
-  RequestVersionOrLower` sur le `HttpClient` partagé de `YavscApiClient`,
-  avec repli h2/h1.1 où QUIC n'est pas disponible (WASM fetch, Android/
-  desktop sans libmsquic).
-* [Tests] `MyFilesPageHeadlessTests` : monte `MyFilesPage` via
-  `NavigationPage` + `Window.Show()` et vérifie que chaque bouton de
-  ligne (Télécharger / Supprimer) a sa `Command` liée, est armé
-  (`CanExecute`) et déclenche l'appel API au clic.
-* [Tests] `Remoting.PasswordToken_carries_name_claim_equal_to_login` :
-  mint un vrai JWT via le token endpoint IdentityServer (password grant,
-  `openid profile`) et asserte que l'access token porte `name`=login et
-  que `GetUserName()` résout vers ce login.
-* [Tests] `FileSystemApiTests.Get_fs_lists_files_stored_under_the_user_login` :
-  découple `sub` et login, téléverse sous le login, et asserte que
-  `GET /api/v1/fs` retourne le fichier (et que le répertoire nommé d'après
-  le `sub` n'existe pas).
-
-### Changed
-
-* [Yavsc.Org] Branchement du `ProfileService` custom
-  (`AddProfileService<ProfileService>()` après
-  `AddAspNetIdentity<ApplicationUser>()`). La classe était du code mort :
-  IdentityServer8 retombait sur son profile service par défaut, qui
-  n'émet que les claims listés dans les `UserClaims` des API resources.
-  `name` n'en faisait jamais partie, donc tout access token était sans
-  `name` et `GetUserName()` résolvait à `null` sur les hosts ressources
-  (Blogs/Api) — cause du 500 sur l'upload MyFiles et du
-  `User.Identity.Name` injoignable. Le service émet désormais
-  `name`=`user.UserName`, `email` et les rôles pour tout client dont
-  les `AllowedScopes` contiennent `profile`, indépendamment du caller.
-* [Yavsc.Server] `ServiceExtensions` : `NameClaimType =
-  JwtClaimTypes.Name`, `MapInboundClaims = false` (conserver les noms
-  courts de claims tels qu'émis).
-* [Yavsc.Blogs] `FileSystemHelpers.EnsureDestinationDirectory` utilise
-  `GetUserName()` (claim `name`) au lieu de `User.Identity.Name` pour
-  la racine de stockage par utilisateur.
-* [Tests] `WebServerFixture` : `AccessTokenType = 0` (Jwt dans IS8 ;
-  1 = Reference, l'inverse de Duende) ; `openid`+`profile` sur le client
-  de test ; réensemencement des identity resources openid/profile dans
-  `ReseedAuthTestData` (un `ResetAndMigrateDatabase` vide le store
-  in-memory partagé et les laissait absentes → `invalid_scope`).
-* [Tests] `TestTokenIssuer.Issue` gagne un paramètre `name` optionnel
-  (défaut = subject) pour refléter la forme production où
-  `sub` (GUID) ≠ `name` (login).
-* [Tests] `BillingServiceTests` : `[Collection("Yavsc Server")]` pour
-  sérialiser avec le build d'hôte qui mute les registres statiques
-  `BillingService`/`Config` (race parallèle pré-existante).
-
-### Fixed
-
-* [Yavsc.Blogs] La liste `GET /api/v1/fs` cherchait sous
-  `{Blog}/{sub-GUID}` (`User.GetUserId()`), alors que l'arbre de
-  stockage perso est indexé par le login partout ailleurs
-  (`EnsureDestinationDirectory` écrit sous `{Blog}/{name-claim}`,
-  le endpoint de téléchargement et les avatars utilisent
-  `user.UserName`). Une fois l'upload corrigé, les fichiers
-  atterrissaient sous `{Blog}/{login}` tandis que la liste cherchait
-  sous `{Blog}/{GUID}` — un arbre vide — d'où la page PostIt
-  « Mes fichiers » qui ne listait rien. `GetDir` résout désormais
-  l'utilisateur en base et liste sous `user.UserName`.
-  `UploadedFile.OwnerId` reste `sub`, donc `EnrichWithFileIds`
-  interpole toujours par `uid`.
-* [PostIt] Boutons d'action des lignes de liste grisés et inactifs au
-  clic (Télécharger / Supprimer / Joindre sur MyFiles ; download/detach
-  sur les listes de pièces jointes de `BillingQueryDetailsPage` et
-  `EstimateEditionPage`). Le binding `$parent[vm:XxxViewModel].Cmd`
-  cherchait un ancêtre CONTRÔLE de type `XxxViewModel` — un viewmodel,
-  pas un contrôle — donc résolvait à `null` et le `Button` restait
-  désactivé (grisé) et inerte au clic. Corrigé en
-  `$parent[ContentPage].((vm:XxxViewModel)DataContext).Cmd` (syntaxe
-  déjà en vigueur dans `CirclesPage` / `EstimateListPage`).
-* [PostIt] Les messages de la barre de statut (`StatusBar`) n'étaient
-  pas sélectionnables/copiables : le texte était un `TextBlock` (non
-  sélectionnable dans Avalonia). Remplacé par `SelectableTextBlock`.
-* [Yavsc.Blogs] La suppression d'un fichier (`DELETE api/v1/fs/{name}`)
-  renvoyait un 40x alors que le fichier était bien supprimé du disque.
-  `DeleteUserDirOrFile` (et `DeleteUserFile`) lisaient
-  `FileInfo.Length` **après** `fi.Delete()` ; or `FileInfo.Length`
-  lève `FileNotFoundException` une fois le fichier disparu — le `catch`
-  du contrôleur transformait cette exception en 400, d'où le message
-  perçu « le fichier n'existe pas sur le serveur » tandis que la
-  suppression avait réussi. La taille est désormais capturée avant la
-  suppression.
-* PostIt default settings
-
-## [1.0.8-rc17] - unstable
-
-Fichiers utilisateur et pièces jointes sur les devis/demandes (PostIt +
-API), système de génération `contrib` (vhosts nginx HTTP/3 edge +
-appsettings jq + QUIC logiciel Kestrel), et correction du bug de
-production où `IsPublished` disparaissait du payload de liste du blog API.
-
-### Added
-
-* [PostIt] Espace de stockage personnel (« MyFiles ») : page de gestion
-  des fichiers de l'utilisateur, entrée depuis la page d'accueil.
-* [PostIt] Pièces jointes aux devis et aux demandes : attachement depuis
-  le détail de demande et la page d'édition de devis.
-* [Yavsc.Api] Endpoints d'attachement de fichiers sur les devis
-  (`EstimateApiController`) et les demandes front-office
-  (`FrontOfficeApiController`).
-* [Yavsc.Api.Client] `UserFilesApiClient` + DTOs associés ; méthodes
-  d'attachement sur `EstimateApiClient` et `FrontOfficeApiClient`.
-* [Yavsc.Server] Modèles `EstimateAttachedFile`, `QueryAttachedFile`,
-  `BlogAttachedFile`, `AttachFileRequest` ; migration EF Core
-  `UserFileAttachments`.
-* [contrib] Système de génération `Makefile` : vhosts nginx HTTP/3 edge
-  (`template.vhost`, `QUIC_OPTS`), appsettings générés via jq
-  (`template.appsettings-{org,api,blogs}.json`, échappement JSON-safe des
-  secrets), QUIC logiciel Kestrel (`Http1AndHttp2AndHttp3`), et
-  `README.nginx.md`.
-* [Tests] Projet `Yavsc.Server.Tests` : tests du service
-  `BlogSpotService.Details` + `ServerServicesFixture` (SQLite `:memory:`
-  par défaut, Npgsql opt-in via `YAVSC_SERVER_TEST_DB_PROVIDER`).
-* [Tests] `IBlogPostWireShapeTests` (forme du wire blog),
-  `EstimateAttachmentsApiTests`, `FrontOfficeQueryAttachmentsApiTests`,
-  `FileSystemApiTests` (pièces jointes et stockage perso).
-* [CI] Intégration Gitleaks / analyse de secrets (`.pre-commit-config.yaml`).
-
-### Changed
-
-* [contrib] `QUIC_OPTS` (`reuseport`) désormais activé uniquement en
-  production sur le vhost Org. La preprod et la prod partageant la même
-  IP, `reuseport` — légal une seule fois par `addr:port` (443/udp) —
-  serait sinon en conflit entre preprod-Org et prod-Org et ferait refuser
-  la config par nginx.
-* [Yavsc.Api.Test] `ApiWebServerFixture` : la connexion admin PostgreSQL
-  provient de la variable d'environnement
-  `YAVSC_API_TEST_NPGSQL_ADMIN_CONNECTION` ; plus de mot de passe en
-  source.
-
-### Fixed
-
-* [Yavsc.Blogs] Bug de production : `IsPublished` était absent du payload
-  de la liste du blog API. Le endpoint `GetBlogspot` retourne
-  `IEnumerable<IBlogPost>` sérialisé par System.Text.Json d'après le type
-  déclaré (l'interface), qui omet les propriétés du type concret —
-  `IsPublished` vivait sur `BlogPost` / `BlogPostDto` mais pas sur
-  `IBlogPost`. PostIt lisait donc `IsPublished == false` pour tout billet,
-  y compris publiés (https://yavsc.pschneider.fr/BlogSpot/Details/13).
-  Corrigé en déclarant `IsPublished` sur `IBlogPost`.
-* [Yavsc.Org] Accès au Swagger UI : les actions MVC scaffoldées de
-  `CommentsController` (Index/Details/…) atterrissaient sur la même route
-  `POST api/v1/blogcomments` que l'action d'API `Post`, provoquant une
-  `SwaggerGeneratorException` (conflit method/path) au chargement de
-  `/swagger`. Corrigé par `[ApiExplorerSettings(IgnoreApi = true)]` sur
-  les actions scaffoldées.

-# Vhosts nginx — génération par `make generate-nginx`
-
-Les vhosts nginx sont **générés** à l'image des unités de service systemd
-(`template.service` + `envsubst` → `generated/*.service`) : un template
-unique `contrib/template.vhost` est substitué par `envsubst` vers
-`contrib/generated/nginx/`, qui est **gitignoré**.
-
-## Rôle de nginx : edge HTTP/3 (plan `contrib/quic.md`)
-
-nginx termine HTTP/3 (QUIC) au edge sur 443/udp, en coexistence avec
-h1/h2 sur 443/tcp. Kestrel reste backend h1/h2 (`proxy_http_version 1.1`).
-Le « QUIC logiciel » Kestrel (`Protocols: Http1AndHttp2AndHttp3` dans les
-`template.appsettings-*.json`) est une capacité complémentaire — non
-joignable par les clients derrière nginx (nginx OSS = upstream h1.1
-uniquement), mais disponible si Kestrel est un jour exposé en direct.
-
-Directives générées (par vhost) :
-```nginx
-listen 443 ssl;          listen [::]:443 ssl;          http2 on;
-listen 443 quic $QUIC_OPTS;   listen [::]:443 quic $QUIC_OPTS;   http3 on;
-add_header Alt-Svc 'h3=":443"; ma=86400' always;
-ssl_protocols TLSv1.3;
-```
-`$QUIC_OPTS = reuseport` sur **Org uniquement**, vide sur Api/Blogs (règle
-`contrib/quic.md` : `reuseport` une seule fois par addr:port, tous vhosts
-confondus).
-
-## Prérequis côté host
-
-1. **nginx avec `http_v3_module`** (≥ 1.25 ; la directive `http3 on;`
-   exige ≥ 1.27.4 — sur une version 1.25–1.27.3, retirer `http3 on;`,
-   `listen ... quic` suffit à activer h3) :
-   ```bash
-   nginx -V 2>&1 | grep -o 'http_v3_module'   # doit être non vide
-   ```
-   Debian 13 « trixie » fournit `nginx` avec `http_v3_module`. Sinon,
-   backports ou `nginx-full`.
-2. **UDP 443 ouvert** :
-   ```bash
-   sudo ufw allow 443/udp
-   sudo ufw status | grep '443/udp'           # → ALLOW
-   ```
-3. **IPv6** : le template émet `listen [::]:443 ...` (et `[::]:80`). Si le
-   host n'a pas d'IPv6, retirer/commenter ces lignes (sinon `nginx -t`
-   échoue sur le bind IPv6).
-4. Certbot / certs Let's Encrypt déjà en place (chemins
-   `/etc/letsencrypt/live/<domain>/{fullchain,privkey}.pem` référencés).
-5. (Optionnel, pour le QUIC logiciel Kestrel) `apt install libmsquic` —
-   sinon Kestrel désactive h3 silencieusement (fallback h1/h2 gracieux).
-
-## Génération
-
-```bash
-cd contrib
-
-# Preprod (défaut) -> generated/nginx/preprod-yavsc{Org,Blogs,Api}
-make generate-nginx
-
-# Production -> generated/nginx/yavsc{Org,Blogs,Api}
-make generate-nginx-prod
-# ou manuellement :
-make generate-nginx APP_INSTALL_ENV=production APP_INSTALL_PREFIX=
-```
-
-Ports backend et `HTTP_HOST` depuis `.preprod.env` / `.production.env`
-(prod Org=83, Api=87, Blogs=85 ; preprod 89/93/91). Schéma backend
-`https` en prod, `http` en preprod.
-
-| Hôte  | Sous-domaine | `reuseport` | Backend prod            | Backend preprod        |
-|-------|--------------|-------------|-------------------------|------------------------|
-| Org   | yavsc        | **oui**     | `https://localhost:83`  | `http://localhost:89`  |
-| Api   | api          | non         | `https://localhost:87`  | `http://localhost:93`  |
-| Blogs | blogs        | non         | `https://localhost:85`  | `http://localhost:91`  |
-
-Domaines : `<prefix><subdomain>.pschneider.fr`
-(prod `yavsc.pschneider.fr` ; preprod `preprod-yavsc.pschneider.fr`).
-
-## Déploiement sur le host
-
-```bash
-sudo cp generated/nginx/yavscOrg  /etc/nginx/sites-available/yavscOrg
-sudo ln -sf /etc/nginx/sites-available/yavscOrg /etc/nginx/sites-enabled/yavscOrg
-# (idem yavscApi, yavscBlogs)
-sudo nginx -t && sudo systemctl reload nginx
-```
-
-## Vérification (sur le host)
-
-```bash
-# 1. Module h3 présent
-nginx -V 2>&1 | grep -o 'http_v3_module'
-
-# 2. UDP 443 ouvert
-sudo ufw status | grep '443/udp'
-
-# 3. En-tête Alt-Svc annoncé
-curl -sI https://yavsc.pschneider.fr/ | grep -i alt-svc   # → h3=":443"
-
-# 4. Requête HTTP/3 effective (curl compilé avec HTTP/3)
-curl -v --http3 https://yavsc.pschneider.fr/ 2>&1 | grep -i 'HTTP/3'
-
-# 5. Fallback h2 et h1 toujours fonctionnels
-curl --http2   https://yavsc.pschneider.fr/ -o /dev/null -w '%{http_code}\n'
-curl --http1.1 https://yavsc.pschneider.fr/ -o /dev/null -w '%{http_code}\n'
-```
-Répéter 3-5 pour `api.pschneider.fr` et `blogs.pschneider.fr` (prod) et
-les trois domaines preprod. Sans curl HTTP/3, un navigateur : DevTools →
-Network → colonne « Protocole » → `h3` après mise à niveau.
-
-## Comment ça marche (template + envsubst)
-
-`contrib/template.vhost` contient les placeholders `$DOMAIN`,
-`$BACKEND_SCHEME`, `$HTTP_HOST`, `$BACKEND_PORT`, `$QUIC_OPTS`. La règle
-`generated/nginx/$(APP_INSTALL_PREFIX)yavsc%` du `Makefile` les substitue
-via `envsubst` avec une **allowlist** :
-
-```makefile
-envsubst '$DOMAIN $BACKEND_SCHEME $HTTP_HOST $BACKEND_PORT $QUIC_OPTS'
-```
-
-Cette allowlist limite la substitution aux 5 variables citées, de sorte
-que les variables nginx intrinsèques (`$host`, `$scheme`, `$remote_addr`,
-`$proxy_add_x_forwarded_for`, `$request_uri`) survivent intactes. Sans
-allowlist, `envsubst` détruirait ces variables nginx.
-
-## Hors périmètre
-
-- `docker-compose` / `Dockerfile` : non touchés (déploiement bare-metal
-  systemd + nginx).
-- Backend HTTP/2 vers Kestrel : nginx open-source ne supporte que
-  HTTP/1.1 en upstream ; on garde `proxy_http_version 1.1`.
-- `ssl_protocols TLSv1.3` (suivant `contrib/quic.md`) désactive TLS 1.2
-  côté TCP aussi. Pour conserver la compat TLS 1.2 sur le fallback TCP,
-  relâcher en `ssl_protocols TLSv1.2 TLSv1.3;` (QUIC reste en 1.3).

-## Défilement de la page des billets
-
-La page `BlogsPage` utilise une grille à hauteur contrainte : l'en-tête
-et les commandes restent visibles, tandis que la liste des billets et
-l'éditeur se partagent l'espace disponible. Un `GridSplitter` permet
-de modifier cette répartition. La liste et l'article défilent séparément.
-
-Dans `MarkdownEditorControl`, AvaloniaEdit gère son propre défilement ;
-l'aperçu Markdown est placé dans un `ScrollViewer`. Ne pas limiter
-la hauteur du `MarkdownViewer` lui-même : son contenu doit pouvoir
-dépasser le viewport pour que les barres automatiques s'activent.
-Ne pas placer cette grille dans un `StackPanel` vertical ou un
-`ScrollViewer` de page, qui lui donnerait une hauteur de mesure illimitée.

-
-    Dans ce camp morne et sauvage
-    Entouré de murs de fer,
