## 4. Technische Randbedingungen
* **Deployment**: Das System wird als Bookmarklet ausgeliefert, das auf der Bessa-Webseite ausgeführt wird.
* **Datenquelle**: Direkte Integration mit der Bessa REST-API (`api.bessa.app/v1`).
* **Datenhaltung**: Clientseitig via `localStorage` (Menü-Cache, Flags, Highlights, Theme) und `sessionStorage` (Auth-Token).
* **Datenhaltung**: Clientseitig via `localStorage` (Menü-Cache, Flags, Highlights, Theme, Auth-Token).
* **Build**: Bash-basiertes Build-Script, das Bookmarklet-URL, Standalone-HTML und Installer-Seite generiert.
* **Versionierung**: SemVer, verwaltet über GitHub Releases/Tags.
* **Tests**: Python-basierte Build-Tests (`python3`) + Node.js-basierte Logik-Tests + Node.js-basierte DOM-Interaktionstests (JSDOM).

## v1.7.1 (2026-03-12)
- 🛡️ **Security**: Kritischer Security-Fix und Härtung:
- **XSS-Schutz**: `innerHTML` durch `textContent` in `renderTagsList` (Actions) und `showErrorModal` (UI-Helpers) ersetzt.
- **XSS-Schutz**: Dynamische Kartenelemente in `createDayCard` validiert.
- **Input-Validierung**: Neue Schlagwörter werden nun auf Länge (2-20 Zeichen) und erlaubte Zeichen (Alphanumerisch + Food-Sonderzeichen) geprüft.
- **GUEST_TOKEN**: Der hardcodierte Gast-Token wurde komplett aus dem Code entfernt. Nicht-eingeloggte Nutzer haben keinen API-Zugriff mehr (Sicherheitsbestimmung).
- **Auth-Guards**: API-Funktionen (`loadMenuDataFromAPI`, `refreshFlaggedItems`) prüfen nun explizit auf vorhandene Authentifizierung vor dem Fetch.
- 🛡️ **Tech**: Sicherheits-Test-Suite `tests/test_security.js` implementiert.
## v1.6.25 (2026-03-12)
- ⚡ **Performance**: Debounced Resize-Listener hinzugefügt. Die Höhen-Synchronisierung der Menü-Karten wird nun auch bei Viewport-Änderungen (z.B. Fenster-Skalierung oder Orientierungswechsel) automatisch und effizient ausgeführt.
- 🧹 **Tech**: `debounce` Utility-Funktion in `utils.js` ergänzt.
