 ## 1. Einleitung
 ### 1.1 Zweck des Systems
-Das System dient als Wrapper und Erweiterung für das Bessa Web-Shop-Portal der Knapp-Kantine (https://web.bessa.app/knapp-kantine). Es ermöglicht den Benutzern, Menüpläne einzusehen, Buchungen automatisiert vorzunehmen und Menüdaten persistent für den öffentlichen Zugriff bereitzustellen, ohne dass jeder Betrachter eigene Zugangsdaten benötigt.
+Das System dient als Erweiterung für das Bessa Web-Shop-Portal der Knapp-Kantine (https://web.bessa.app/knapp-kantine). Es verbessert die Benutzererfahrung durch eine übersichtliche Wochenansicht, vereinfachte Bestellvorgänge, Kostentransparenz und proaktive Benachrichtigungen.
 
 ### 1.2 High-Level-Scope
-Das System umfasst einen automatisierten Scraper, eine API zur Datenbereitstellung, einen persistenten Dateispeicher für erfasste Menüs und ein Frontend-Dashboard zur Visualisierung der Kantinen-Wochenpläne.
+Das System umfasst die Darstellung von Menüplänen in einer Wochenübersicht, die Verwaltung von Bestellungen und Stornierungen, ein Benachrichtigungssystem für Verfügbarkeitsänderungen, personalisierte Menü-Highlights sowie ein automatisches Update-Management.

+*   **Deployment**: Das System wird als Bookmarklet ausgeliefert, das auf der Bessa-Webseite ausgeführt wird.
-*   **Engine**: Direkte API-Integration (Reverse Engineering der Bessa API) für maximale Performance und Zuverlässigkeit.
+*   **Datenquelle**: Direkte Integration mit der Bessa REST-API (`api.bessa.app/v1`).
-*   **Datenspeicher**: Dateibasierter JSON-Store für persistente Daten + In-Memory Caching.
+*   **Datenhaltung**: Clientseitig via `localStorage` (Menü-Cache, Flags, Highlights, Theme) und `sessionStorage` (Auth-Token).
-*   **Schnittstellen**: REST API (`/api/bookings`, `/api/status`, `/api/order`).
+*   **Build**: Bash-basiertes Build-Script, das Bookmarklet-URL, Standalone-HTML und Installer-Seite generiert.
-*   **Runtime**: Node.js Umgebung, Docker-ready.
+*   **Versionierung**: SemVer, verwaltet über GitHub Releases/Tags.
+*   **Tests**: Python-basierte Build-Tests (`python3`) + Node.js-basierte Logik-Tests + Node.js-basierte DOM-Interaktionstests (JSDOM).

+## v1.6.11 (2026-03-09)
+- 🔄 **Refactor**: Trennung der Zeitstempel für die Hauptaktualisierung (Header) und die Benachrichtigungsprüfung (Bell-Icon). Das Polling aktualisiert nun nicht mehr fälschlicherweise die "Aktualisiert am"-Zeit im Header.
+- 🏷️ **Metadata**: Version auf v1.6.11 angehoben.
+
+## v1.6.10 (2026-03-09)
+- **Feature**: Robuste Kurs-Erkennung in zweisprachigen Menüs ([FR-121](REQUIREMENTS.md#FR-121)).
+- **Fix**: Verhindert das Verschieben von Gängen bei fehlenden englischen Übersetzungen.
+- **Improved**: Heuristik-Split erkennt nun zuverlässiger den Übergang von Englisch zurück zu Deutsch (z.B. bei "Achtung"-Hinweisen)
+
+## v1.6.9 (2026-03-09)
+- 🐛 **Bugfix**: Fehlerhafte Zeitangabe beim Bell-Icon ("vor 291h") behoben. Der Tooltip wird nun minütlich aktualisiert und nach jeder Menü-Prüfung korrekt neu gesetzt.
+- 🔄 **Refactor**: Zeitstempel-Management für die letzte Aktualisierung vereinheitlicht und im `localStorage` persistiert.
+
+## v1.6.8 (2026-03-06)
+- ⚡ **Performance**: Das JavaScript für das Kantinen-Bookmarklet wird nun beim Build-Prozess (via Terser) minimiert, was die Länge der injizierten URL spürbar reduziert.
+
+## v1.6.7 (2026-03-06)
+- 🎨 **Style**: Das neue Header-Logo (`favicon_base.png`) wird nun konsequent auf 40x40px generiert und gerendert.
+
+## v1.6.6 (2026-03-06)
+- 🎨 **Style**: Den Schatten und den hervorstehenden Karten-Effekt für bestellte Menüs an vergangenen Tagen komplett entfernt - verbleiben nun visuell flach und unaufdringlich wie nicht-bestellte Menüs.
+
+## v1.6.5 (2026-03-06)
+- ✨ **Feature**: Das `restaurant_menu` Icon im Header wurde durch das neue `favicon_base.png` Logo ersetzt, passend zur Textgröße skaliert.
+- 🎨 **Style**: Violette Umrahmung (Bestellt-Markierung) an vergangenen Tagen entfernt, um den Fokus auf aktuelle und zukünftige Bestellungen zu lenken.
+- 🎨 **Style**: Der Glow-Effekt für am heutigen Tag bestellte Menüs wurde intensiviert.
+
+## v1.6.4 (2026-03-05)
+- ✨ **Feature**: Sprach-Lexikon (DE/EN) massiv erweitert um österreichische Begriffe (Nockerl, Fleckerl, Topfen, Mohn, Most etc.) und gängige Tippfehler aus dem Bessa-System (trukey, coffe, oveb etc.).
+- 🧹 **Cleanup**: Sprach-Lexikon dedupliziert und alphabetisch sortiert für bessere Performance und Wartbarkeit.
+- 🐛 **Bugfix**: Trennung von zweisprachigen Menüs (`splitLanguage`) verbessert: Erfasst nun auch Schrägstriche ohne Leerzeichen (z.B. `Suppe/Soup`).
+- 🐛 **Bugfix**: Fehlerhafte Badge-Anzeige korrigiert (Variable `count` vs `orderCount`).
+
+## v1.6.3 (2026-03-05)
+- ✨ **Chore**: Slogan im Footer aktualisiert ("Jetzt Bessa Einfach! • Knapp-Kantine Wrapper • 2026 by Kaufis-Kitchen") und Footer-Höhe für mehr Platzierung optimiert.
+
+## v1.6.2 (2026-03-05)
+- ✨ **Feature**: Wochentags-Header (Montag, Dienstag etc.) scrollen nun als "Sticky Header" mit und bleiben am oberen Bildschirmrand haften.
+  - Das Layout clippt scrollende Speisen ordentlich darunter weg.
+  - Vollständiges Viewport-Scrolling: Das Layout nutzt nun die ganze Höhe aus (`100dvh`), wodurch Scrollbalken sauber am Rand positioniert sind.
+- 🐛 **Bugfix**: Probleme mit Bessa's default `overflow` Verhalten behoben, das `position: sticky` auf iOS/WebKit-Browsern blockierte.
+
+## v1.6.0 (2026-03-04)
+- ✨ **Feature**: Sprachfilter für zweisprachige Menübeschreibungen. Neuer DE/EN/ALL Toggle im Header ermöglicht das Umschalten zwischen Deutsch, Englisch und dem vollen Originaltext. Allergen-Codes werden in allen Modi angezeigt. Einstellung wird persistent gespeichert.
+
+## v1.5.1 (2026-03-04)
+- 🐛 **Bugfix**: Freitagsbestellungen schlugen fehl ("Onlinebestellung sind nicht verfügbar"). Ursache: Der Order-Payload verwendete `preorder: false` und eine falsche Uhrzeit (`T10:00:00.000Z` statt `T10:30:00Z`). Beides wurde anhand der originalen Bessa-API korrigiert.
+
+## v1.5.0 (2026-02-26)
+Das große "Quality of Life"-Update! Zusammenfassung aller Features und Fixes seit v1.4.0:
+
+- ✨ **Bestellhistorie**: Übersichtliche Historie direkt in der App – gruppiert nach Jahr/Monat, inklusive Summen, Stati (Offen/Abgeschlossen/Storniert) und Delta-Cache für rasantes Laden.
+- ⚡ **Smart Cache & Performance**: Massive Reduzierung von API-Calls und Ladezeiten durch intelligenten lokalen Cache. Das Bookmarklet startet nun praktisch verzögerungsfrei.
+- 🔄 **GitHub Release Management**: In-App Versions-Menü mit Auto-Update Check (`🆕` Icon). Umschalten zwischen "Stable" und "Dev" Versionen sowie Downgrade-Möglichkeit direkt über die GitHub API.
+- 🌟 **Smart Highlights & UX**: Speisen-Favoriten leuchten nun im Design-Violett und erhalten Feature-Badges. Der Bestell-Badge für nächste Woche filtert nun intelligent personalisierte Highlights voraus.
+- 🔔 **Bestell-Warnung & Notifications**: Der System-Alarm berücksichtigt nun Sessions korrekt, zeigt dynamische Farbwechsel (gelb/grün/rot) und warnt verlässlich vor dem Bestellschluss (10:00 Uhr). Altlasten von Vortagen werden automatisch geputzt.
+- 🎨 **Eigenes Favicon**: Das Bookmarklet und der Installer haben nun ein eigenes Icon (Dreieck mit Besteck), das beim Hineinziehen in die Lesezeichenleiste übernommen wird (dynamisch generiert als lokales PNG).
+- 🧹 **Lokaler Cache-Clear**: Ein in das Versions-Menü eingebauter "Papierkorb", der ausschließlich fehlerhafte Kantinen-Caches putzt, ohne dabei versehentlich die aktive Bessa-Host-Session zu zerstören.
+- 🔒 **Sitzungs-Persistenz**: Die Login-Session überdauert jetzt neue Tabs, Fenster und Version-Upgrades reibungslos durch den Wechsel auf `localStorage`.
+- 🛡️ **Testing & Stabilität**: Vollautomatische DOM- und Logik-Testing-Suites in der Release-Pipeline integriert. Fehlerhafte UI-Buttons gehören der Vergangenheit an.
+
+
+## v1.4.0 (2026-02-22)
+- **Feature**: Bestellhistorie per Knopfdruck abrufbar. Übersichtliche Darstellung, gruppiert nach Monaten und Kalenderwochen, inklusive Stornos. 📜✨
+
+## v1.3.2 (2026-02-19)
+- **Fix**: Falsche Anzahl an Highlight-Menüs im "Nächste Woche"-Badge korrigiert (zählte alle Menüs statt nur Highlights). 🐛
+
+## v1.3.1 (2026-02-17)
+- **Feature**: Smart Cache – API-Refresh beim Start wird übersprungen wenn Daten für die aktuelle KW vorhanden und Cache < 1h alt ist. ⚡
+
+## v1.3.0 (2026-02-16)
+- **Feature**: GitHub Release Management 📦
+  - Version-Menü: Klick auf Versionsnummer zeigt alle verfügbaren Versionen
+  - Dev-Mode Toggle: Zwischen Releases (stabil) und Tags (dev) wechseln
+  - Downgrade-Support: Jede Version hat einen eigenen Installer-Link
+  - Update-Check nutzt jetzt die GitHub API statt `version.txt`
+  - GitHub PAT für höheres API-Rate-Limit (5000/h)
+  - SemVer-Check: Update-Icon nur bei wirklich neuerer Version
+
+## v1.2.9 (2026-02-16)
+
+## v1.2.8 (2026-02-16)
+- **Debug**: Weiteres Logging (Fetch-Status, Start-Log) zur Fehlersuche. 🔎
+
+## v1.2.7 (2026-02-16)
+- **Debug**: Verbose Logging für Update-Check eingebaut. 🐞
+
+## v1.2.6 (2026-02-16)
+- **Test**: Version Bump zum Testen der Live-Update-Erkennung. 🧪
+
+## v1.2.5 (2026-02-16)
+- **Refactor**: Update-Erkennung komplett überarbeitet (stündlicher Check, diskretes 🆕 Icon im Header, kein Banner mehr). 🔄
+- **Cleanup**: Ungenutzter CSS-Code und Netzwerk-Traffic reduziert. 🧹
+- **Fix**: Highlight-Logik stabilisiert (keine falschen Matches bei leeren Tags). 🏷️
+
+## v1.2.4 (2026-02-16)
+- **Feature**: Gefundene Highlights werden jetzt direkt im Menü als Badge angezeigt. 🏷️
+
+## v1.2.3 (2026-02-16)
+- **Fix**: Update-Icon ist jetzt klickbar und führt direkt zum Installer. 🔗
+- **Dev**: Unit-Tests für Update-Logik im Build integriert. 🛡️
+
+## v1.2.2 (2026-02-16)
+- **UX**: Installer-Changelog jetzt einklappbar für mehr Übersicht. 📂
+
+## v1.2.1 (2026-02-16)
+- **Fix**: Smart Highlights werden jetzt korrekt auf Menü-Items angewendet (`checkHighlight` in `createDayCard`). 🌟
+- **Feature**: Mock-Daten (`mock-data.js`) für Standalone-Tests eingebaut. 🧪
+- **Style**: Highlight-Glow mit blauer Puls-Animation (`blue-pulse`) überarbeitet. 💎
+- **Style**: Tag-Badges konsistent mit Badge-System gestaltet. 🏷️
+- **Style**: "Hinzufügen"-Button (`#btn-add-tag`) als Primary-Button gestylt. 🎨
+- **Style**: Modal-Body Padding und Input-Font korrigiert. 🔧
+- **Docs**: README Projektstruktur mit Tabelle für `dist/`-Artefakte ergänzt. 📖
+
+## v1.2.0 (2026-02-16)
+- **Feature**: Bessere UX im Installer (Button oben, Log unten, Features aktualisiert). 💅
+- **Tech**: Build-Tests hinzugefügt. 🧪
+- **Fix**: Encoding-Probleme final behoben (dank Python Buildlogic). 🐍
+
+## v1.1.2 (2026-02-16)
+- **Fix**: Encoding-Problem beim Bookmarklet behoben (URL Malformed Error). 🔗
