+# Appearance 17F — Mode Soleil
+
+Le profil Soleil augmente la visibilité de QuickShell et SwayFX. Il ne modifie
+ni le fond d'écran, ni la luminosité, ni les thèmes GTK, Qt, Kitty, Neovim et
+Firefox. Ces cinq familles d'applications relèvent obligatoirement de 17G ;
+17F ne constitue donc pas une intégration complète du bureau clair.
+
+## État et priorité
+
+`preferences.json` et `effective.json` utilisent le schéma 4. Les anciennes
+préférences migrent vers `sunMode=false`, `sunVariant=light`,
+`sunDarkFlavor=mocha`. Seuls `frappe`, `macchiato` et `mocha` sont admis pour
+`sunDarkFlavor`. Les coordonnées Night Light restent locales et intactes.
+
+`themeMode`, `manualFlavor` et `wallpaperAnalysis` décrivent le choix normal.
+La résolution centrale calcule d'abord ce flavor normal, puis applique la
+priorité Soleil : `sun-light` donne Latte ; `sun-dark` donne
+`sunDarkFlavor` ; Soleil désactivé restitue le flavor normal. Aucun instantané
+des préférences normales n'est utilisé. `effectiveDark` dérive du flavor,
+`effectiveHighContrast` vaut exactement `sunMode`, et `effectiveAccent` reste
+Lavender. `effectiveMode` vaut `normal`, `sun-light` ou `sun-dark`.
+
+Une modification effective du profil ou du flavor augmente `revision` une
+fois. Un changement de `sunDarkFlavor` lorsque Soleil est désactivé est
+persisté sans révision visuelle. Les consommateurs 17G devront utiliser
+`effectiveFlavor`, `effectiveAccent`, `effectiveDark`,
+`effectiveHighContrast`, `effectiveMode` et `revision` comme source unique.
+Un futur `AppThemeSynchronizer` distribuera cet état à ses adaptateurs GTK,
+Qt, Kitty, Neovim et Firefox ; aucune logique spécifique à ces applications
+n'appartient à `Theme.qml`.
+
+## Transaction et reprise
+
+`wallpaper-manager.py` tient le verrou Appearance commun. Il résout l'état,
+écrit atomiquement `generated/theme.conf` et éventuellement
+`generated/wallpaper.conf`, valide Sway, recharge SwayFX, vérifie le fond si
+nécessaire, publie `effective.json`, réconcilie le service Night Light,
+réapplique les opacités existantes par `--refresh`, écrit les préférences,
+puis publie l'état QuickShell via IPC. En cas d'échec, il restaure les octets
+précédents des fichiers et de l'état, recharge Sway, rétablit Night Light et
+les opacités, puis renvoie une erreur. Les transitions sont sérialisées ; les
+contrôles QML attendent la fin de la transaction.
+
+Le listener d'opacité lit l'état uniquement à chaque événement fenêtre ;
+`--refresh` lit une fois lors d'un changement de profil. Normal utilise
+focused `1.0`, inactive `0.85` ; Soleil utilise `1.0` pour les deux. SwayFX
+consomme les variables du générateur dans son unique bloc `layer_effects` :
+blur de la barre `enable` en normal, `disable` en Soleil. Le rayon d'ombre
+passe de 10 à 4 et les couleurs d'ombre sont renforcées en Soleil. Les
+bordures restent de 2 px.
+
+Le lanceur de `wlsunset.service` lit `effective.json` avant tout démarrage :
+en Soleil, il ne lance pas de correction gamma. La préférence Off, Auto ou On
+reste intacte ; en sortie de Soleil le service est réconcilié selon cette
+préférence. Au redémarrage de QuickShell, Appearance se réconcilie avant Night
+Light et reprend la révision persistée. Le repli versionné Mocha reste valide
+sans fichiers générés.
+
+## Contraste et limites
+
+La barre QuickShell passe de `235/255` en normal à `1,0` en Soleil ; les popups
+restent opaques (`1,0`) dans les deux profils. Les rôles `border`,
+`strongBorder`, `outline`, `emphasisBackground`, `separator`,
+`buttonBackground`, `buttonHover`, `secondaryForeground`, `inputBorder`
+et `shadow` dérivent de la palette
+Catppuccin et du contraste effectif. L'accent Lavender et `onAccent` suivent
+le moteur 17B. Les ratios WCAG des paires principales sont :
+
+| Flavor Soleil | texte/panel | secondaire/panel | texte/popup | onAccent/accent | texte/input |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| Latte | 7,06 | 7,06 | 7,06 | 6,60 | 5,17 |
+| Frappé | 8,06 | 8,06 | 8,06 | 11,47 | 6,19 |
+| Macchiato | 9,92 | 9,92 | 9,92 | 11,65 | 7,55 |
+| Mocha | 11,34 | 11,34 | 11,34 | 11,74 | 8,69 |
+
+La paire sélectionnée reprend `onAccent/accent`. Les bordures et séparateurs
+sont décoratifs ; le seuil de texte AA de 4,5:1 ne s'y applique pas. Les
+icônes colorées des applications dans le tray ne sont pas recolorées.
+La lisibilité réelle en plein soleil exige une validation sur l'écran physique.

+# Localisation & heure
+
+La page **Réglages rapides → Apparence → Localisation & heure** sépare le fuseau horaire système de la position solaire utilisée par wlsunset. Le fuseau vient exclusivement de `timedatectl` ; les coordonnées, les lieux enregistrés et le nom actif facultatif viennent de `~/.config/labfy-appearance/preferences.json` (mode 0600). Aucun service réseau, aucune détection IP et aucun lieu personnel ne font partie du dépôt.
+
+## Données locales et voyage
+
+`location-time-manager.py` lit `/usr/share/zoneinfo/zone1970.tab`, convertit ses coordonnées compactes et vérifie les identifiants dans `/usr/share/zoneinfo`. La recherche est locale et instantanée. Les coordonnées de cette base sont des points représentatifs associés aux fuseaux ; elles ne sont pas forcément la position exacte de l'utilisateur. La position manuelle accepte une latitude de −90 à 90 et une longitude de −180 à 180. La liste facultative `savedLocations` est limitée à 100 entrées validées et permet de réutiliser un choix, mais ouvre toujours un résumé avant application. `activeLocationName` est un libellé facultatif sans effet sur le calcul.
+
+Une sélection propose **Appliquer les deux**, **Fuseau uniquement** et **Position solaire uniquement**. Le clic dans la liste ne change rien. La préférence de thème, le fond d'écran et le mode Night Light ne changent pas. Le nom actif n'est qu'un libellé d'interface.
+
+## Privilèges et transaction
+
+`timedatectl set-timezone` est appelé directement, avec un tableau d'arguments, via l'authentification Polkit standard de la session. L'agent graphique `polkit-gnome` est lancé au démarrage Sway. QuickShell ne reçoit jamais le mot de passe, ne dispose d'aucune permission root permanente et ne modifie jamais `/etc/localtime` directement. Si l'authentification est annulée ou indisponible, l'opération échoue sans écrire la position solaire.
+
+L'application combinée valide d'abord les entrées, mémorise l'état précédent, change le fuseau, écrit la position locale, réconcilie Night Light en Auto, puis vérifie le fuseau. Un échec de fuseau laisse la position intacte. Un échec ultérieur restaure la préférence et tente de restaurer le fuseau et le service. Un échec de rollback est affiché comme erreur explicite.
+
+## Night Light et persistance
+
+En Auto hors Mode Soleil, la nouvelle position redémarre l'unique `wlsunset.service`. En mode Activée, la température forcée reste active et la position est seulement enregistrée. En mode Désactivée ou pendant le Mode Soleil, aucune instance n'est démarrée. À la sortie du Mode Soleil ou à la prochaine session Auto, wlsunset relit la nouvelle position. Changer seulement le fuseau ne modifie jamais les coordonnées : wlsunset utilise le temps système et les coordonnées, pas une association implicite ville/fuseau.
+
+Le fuseau persiste via `systemd-timedated`, la position via les préférences. En mode solaire, le [code de wlsunset](https://github.com/kennylevinsen/wlsunset/blob/master/main.c) déduit le jour de la longitude et calcule les événements avec l'heure système UTC ; son décalage de fuseau n'est utilisé que pour l'horaire manuel (`longitude_time_offset` et `wlrun`). Un changement de fuseau seul ne nécessite donc pas de redémarrer Auto ni de modifier les coordonnées. `SystemClock` est rafraîchi à la publication d'un changement de fuseau et continue son tick minute normal. Aucun paramètre horaire propre à Firefox, Kitty, Neovim, GTK ou Qt n'est écrit.
