Rebuild the editor around one sidebar and play motion by default in 1.11.0

The editor follows the Flatsome UX Builder: dark top bar with the device
switch, one sidebar with tabs for elements, structure and page, an element
view with breadcrumbs, property tabs and actions, element cards, a context
menu in the preview and keyboard shortcuts that also work inside the preview.

Entrance and hover effects play for every visitor unless the website chooses
to respect the browser's reduced-motion preference (setting "motion", class
"motion-respect" on <html>). Waiting blocks stay hidden until they scroll into
view and are shown at once when the reader jumps past them.

+## Editor mit einer Seitenleiste und Bewegung wie Flatsome (ab 1.11.0)
+
+Der Editor folgt jetzt dem Aufbau des Flatsome UX Builders: eine dunkle Kopfzeile mit Gerätewahl in der Mitte, Rückgängig/Wiederholen, Bewegung abspielen, Speichern und Veröffentlichen; links **eine** Seitenleiste mit den Reitern **Elemente**, **Struktur** und **Seite**; rechts die Vorschau. Ein Klick auf ein Element in der Vorschau öffnet seine Optionen in der Seitenleiste: Name, Pfad (Seite › Sektion › Zeile), die Reiter Inhalt/Design/Erweitert, unten Verschieben, Duplizieren, Löschen. **‹** wählt das übergeordnete Element, **＋** fügt in einen Container ein oder direkt hinter das Element, **✕** oder Escape hebt die Auswahl auf. Rechtsklick in der Vorschau öffnet ein Kontextmenü mit denselben Aktionen. Entf löscht das gewählte Element, sofern kein Feld den Fokus hat.
+
+Die Elemente stehen als Kartenraster mit Symbol und Namen; was an der gewählten Stelle nicht passt, ist ausgegraut und sagt beim Überfahren warum. In der Struktur wählt ein Klick nur aus, **Bearbeiten** oder Doppelklick öffnet das Element. Die Sichtbarkeit je Gerät steht jetzt am Ende von Inhalt und Erweitert. Die verstellbaren Panelbreiten entfallen.
+
+**Bewegung:** Einblendungen, Hover-Bewegungen und Slider-Automatik spielen standardmäßig bei jedem Besucher, wie bei Flatsome und den meisten Websites. Manche Browser melden „Bewegung reduzieren“, ohne dass jemand es eingestellt hat; bisher blieb dann jede Einblendung aus. Unter **Einstellungen → Einblendungen und Hover-Bewegungen** lässt sich „Browservorgabe beachten“ wählen; dann trägt `<html>` die Klasse `motion-respect`, und Skript wie CSS halten sich wieder an die Vorgabe. Einblendungen verstecken einen Block, bis er ins Bild scrollt, und blenden ihn dann von unsichtbar ein; wer per Sprungmarke oder schnellem Scrollen an einem Block vorbeikommt, sieht ihn sofort. Ohne JavaScript ist alles sichtbar.
+
+Gezielt prüfen (isolierte Kopien; PHP mit SQLite3-Erweiterung):
+
+```powershell
+$env:PHP_BINARY = 'C:\php84\php.exe'
+node scripts/motion-check.mjs

 ## Formularbutton und Bewegungseffekte (ab 1.10.1)
 
 „Absenden“ übernimmt den Website-Standardbutton aus Design/Typografie: Form, Darstellung, Größe, Schrift und normale/Hover-Farben. Bestehende Formulare aktualisieren sich ohne erneutes Speichern; der Button hat seine natürliche Breite statt automatisch die gesamte Formularbreite. Formularfelder, Versand und Validierung bleiben unverändert.

+## ADR 091 – Eine Seitenleiste wie im Flatsome UX Builder; Bewegung spielt, bis die Website etwas anderes sagt (14.09.2026)
+
+**Editor.** Drei Panels nebeneinander – Werkzeugkasten und Struktur links, Vorschau, Eigenschaften rechts – zeigten immer alles und damit nichts; Umut fand sich nicht zurecht, im Flatsome UX Builder schon. Der Editor übernimmt dessen Rhythmus: eine Seitenleiste, die genau eine Sache zeigt. Reiter für Elemente, Struktur und Seite; ein gewähltes Element öffnet seine eigene Ansicht mit Name, Pfad, den drei Eigenschaftenreitern und den Aktionen am Fuß und gibt sie beim Abwählen wieder frei. Die Reiter bleiben dabei erreichbar, damit Bibliothek und Baum einen Klick entfernt sind. Die Struktur wählt beim Klick nur aus und öffnet erst über „Bearbeiten“; sonst verschwände der Baum bei jedem Schritt. Rechtsklick in der Vorschau öffnet ein Kontextmenü im Editor-Dokument, dessen Position einmal aus Rahmen und Maßstab umgerechnet wird. Tastenkürzel gelten auch, wenn der Fokus in der Vorschau liegt: derselbe Handler hängt am Fenster und an jedem Vorschau-Dokument. Die Auswahl scrollt nur das Vorschau-Fenster, nicht per `scrollIntoView` – das zog das Editor-Dokument mit und schob die Kopfzeile aus dem Bild. Die verstellbaren Panelbreiten entfallen; eine feste Leiste ist der einfachere Vertrag. Bestehende IDs (`#library`, `#structure`, `#properties`, `#preview`, `#save-status` …) bleiben, die Browserprüfung wechselt die Ansicht über Helfer statt über versteckte Elemente zu klicken.
+
+**Bewegung.** Bisher entschied allein die Browservorgabe `prefers-reduced-motion`, und die meldete Umuts Chrome als aktiv, ohne dass er sie gesetzt hatte; andere Websites bewegen sich bei ihm, weil sie die Vorgabe ignorieren. Die Entscheidung gehört der Website: Einstellung `motion` mit `always` (Standard, Flatsome-Verhalten) und `respect`. Der Server druckt bei `respect` die Klasse `motion-respect` auf `<html>`; `motion.js` und `slider.js` fragen `Klasse && Vorgabe`, das CSS schreibt die Hover-Fahrten unbedingt und nimmt sie in einem Überschreibblock `@media (prefers-reduced-motion: reduce) { html.motion-respect … { transform: none; transition: none } }` zurück – Farben und Schatten bleiben, nur die Fahrt fällt weg. Einblendungen verstecken einen wartenden Block per Inline-`opacity:0` (nur mit Skript, nur wenn Bewegung erlaubt ist) und blenden ihn mit `fill: backwards` von unsichtbar ein; ein `scroll`-Handler zeigt sofort, was oberhalb des Bildes liegt, weil ein Sprung per Sprungmarke oder Wiederherstellung sonst Blöcke dauerhaft unsichtbar ließe. Beim Abschalten (Präferenzwechsel unter `respect`, Editor-Stopp) werden alle versteckten Blöcke wieder eingeblendet. Barrierefreiheit: Einblendungen dauern unter einer Sekunde, blinken nicht und lassen sich per Einstellung an die Vorgabe binden; Lighthouse misst diese Vorgabe nicht. Kein Schema- und kein Datenbankwechsel: `motion` fällt bei fehlendem Wert auf `always` zurück.
+
 ## ADR 090 – Releasecache bleibt für laufende Updateanfragen erhalten (14.09.2026)
 
 Der echte HTTP-Updatepfad von 1.10.0 nach 1.10.1 reproduziert Umuts 500 auf `/admin/system/archiv`: Die Dateien sind bereits erfolgreich ersetzt, dann entfernt `ArchiveUpdate` den gesamten `var/cache`. Symfony lädt beim Abschluss weitere Dienste aus dem kompilierten Container nach und findet deren PHP-Dateien nicht mehr. Eine frische Installation und isolierte Updater-Rückgabewerte decken diesen Fehler nicht ab.

 # Projektstatus
 
+## 1.11.0 – Editor mit einer Seitenleiste nach Flatsome-Vorbild, Bewegung spielt standardmäßig (14.09.2026)
+
+**Anlass:** Umut fand den Editor mit drei Panels unübersichtlich und kam mit dem Flatsome UX Builder zurecht; außerdem liefen die Einblendungen in seinem Chrome nicht, weil der Browser „Bewegung reduzieren“ meldet, obwohl er das nicht eingestellt hat – andere Websites bewegen sich bei ihm.
+
+**Umgesetzt:** Editor-Gerüst neu (`templates/admin/editor.html.twig`, `editor.css`, `editor.js`): dunkle Kopfzeile mit Gerätewahl in der Mitte, eine Seitenleiste mit den Reitern Elemente/Struktur/Seite und einer Elementansicht (Name, Pfad, Inhalt/Design/Erweitert, Aktionen unten, ‹ zum Elternelement, ＋ zum Einfügen, ✕ zum Schließen), Elementkarten im Raster, Kontextmenü per Rechtsklick in der Vorschau, Escape/Entf-Tasten auch bei Fokus in der Vorschau, „Bearbeiten“ neben dem gewählten Strukturknoten. Panelbreiten und der Werkzeugkasten-Umschalter entfallen. Sichtbarkeit am Ende von Inhalt und Erweitert. Bewegung: Website-Einstellung `motion` (`always` Standard, `respect`), Klasse `motion-respect` auf `<html>`, `motion.js` versteckt wartende Blöcke und blendet sie von unsichtbar ein, zeigt übersprungene Blöcke sofort; Hover-CSS ohne Medienschranke, Überschreibblock nur für `motion-respect`; `slider.js` folgt derselben Regel. ADR 091.
+
+**Geprüft:** `scripts/motion-check.mjs` auf isolierter Pilotkopie (1600/390 px) erfolgreich: Warten außerhalb des Bildes, Start beim Scrollen, einmalige Wiedergabe, Richtungen, gespeicherter Hover, Standard spielt unter emuliertem „reduce“, `motion-respect` unterdrückt und nimmt wieder auf, Editorhinweis nur bei `motion-respect`. In der App-Vorschau mit realen Kant-IT-Daten: Auswahl, Design-Reiter, Kontextmenü, ＋-Einfügen (Zeile → nur Spalte erlaubt, Spalte → Überschrift), Entf, Strg+Z, Tablet-Ansicht, öffentliche Startseite mit 14 Einblendungen (7 warten, alle sichtbar nach Sprung ans Seitenende), keine JavaScript-Fehler. 33 JavaScript-Tests, Twig-Lint der geänderten Vorlagen, angepasster CSS-Test in `CmsTest`. `scripts/editor-check.mjs` auf die eine Seitenleiste umgestellt (Reiter-Helfer, Bearbeiten im Baum, Flatsome-Modus in der Sandbox) und vollständig erfolgreich, einschließlich aller axe-Prüfungen (Desktop- und Mobil-Editor, Mediathek, Verwaltungsseiten), Entwurf/Veröffentlichung, Konflikt und Einwilligung.
+
+**Bekannt / Grenzen:** `CmsTest::testAnyPublishedPageCanBecomeTheRootAndEverythingFollows` schlägt bereits ohne diese Änderungen fehl (Menülink `Start` fehlt) – nicht Teil dieses Schritts. Kein neuer Lighthouse-Lauf. Die Ursache der Browsermeldung in Umuts Chrome bleibt offen; die Website hängt nicht mehr davon ab. Noch nicht committed oder veröffentlicht.

 ## 1.10.2 – Fehler 500 beim Abschluss des Archiv-Updateaufrufs (14.09.2026)
 
 **Reproduziert und korrigiert:** Echter Produktionsmodus mit den vollständigen Paketen 1.10.0 → 1.10.1: Update-POST HTTP 500 nach erfolgreichem Dateitausch, fehlende PHP-Dienste im gerade gelöschten Containercache. Systemseite anschließend HTTP 200, Migrationsabschluss HTTP 302, öffentliche Seite danach HTTP 200. Ursache und Übergang: ADR 090. Der Kernel hält nun seinen Cachepfad pro Anfrage fest und verwendet für jede Releasefassung ein eigenes Verzeichnis. Der Archiv-Updater entfernt keine Dateien, die die laufende Anfrage noch benötigt.
 
-**Bisher geprüft:** Gegenprobe mit korrigiertem Updater: POST 302, System 200, Abschluss 302, öffentlich 200. 16 gezielte PHP-Tests / 105 Assertions für Archive, Cachepfad und Systemverwaltung erfolgreich. Neuer wiederverwendbarer Paket-HTTP-Test reproduziert den alten Fehler sowie den erfolgreichen Wiederaufnahmeweg. Die Originaldatenbank bleibt unberührt.
+**Geprüft:** 28 PHP-Tests / 347 Assertions für Archiv- und Git-Updater, Cachepfad, Systemverwaltung und Installation erfolgreich. Wiederverwendbarer Paket-HTTP-Test reproduziert 1.10.0 → 1.10.1 mit 500 sowie den erfolgreichen Wiederaufnahmeweg (`var/archive-check-f00fc15412`). Mit dem echten Zielpaket 1.10.2: Übergang aus 1.10.1 weiterhin einmalig POST 500, danach System 200, Abschluss 302, öffentlich 200 (`var/archive-check-316de9113a`). Korrigierter Paket-Updater mit ausschließlich synthetischer vorheriger Versionsnummer: POST 302, System 200, Abschluss 302, öffentlich 200, keine fehlenden Cachedienste (`var/archive-check-8637d9310e`). Sitzung, Wartungszustand, Sicherung, Versionswechsel und unveränderte Originaldatenbank geprüft. Produktionscontainer, Cache-Warmup, PHP-Stil und JavaScript-Syntax erfolgreich.
 
-**Release / nächster Schritt:** Paket 1.10.2 bauen und den Übergang aus 1.10.1 sowie einen weiteren Updateaufruf aus dem korrigierten Stand mit diesem Paket prüfen. Noch nicht veröffentlicht. Der bereits installierte alte Updater kann beim Einspielen dieser Reparatur einmalig weiter 500 ausgeben; anschließend `/admin/system` direkt öffnen und die angebotenen Migrationen abschließen. Das ist im Pakettest ausdrücklich zu prüfen. Kein Zugriff auf Produktionsprotokolle und keine Produktionsänderung durch diese Diagnose; Startseite und Anmeldung aktuell HTTP 200.
+**Veröffentlicht:** Commit `7c1c86b`, Tag `v1.10.2`, [Release 1.10.2](https://git.kant-it.de/kantarci/KantSites/releases/tag/v1.10.2) auf origin und als neuestes stabiles Release geprüft. Paket aus dem exakten Commit, 3543 Archivdateien und 221 Quelldateien bytegenau geprüft; nur Produktionsabhängigkeiten. Frischer Installer HTTP 200, Container und Cache-Warmup auch im Release erfolgreich. ZIP, Prüfsumme und Installer anonym heruntergeladen und mit den lokalen Artefakten verglichen. ZIP-SHA-256: `733f591c143e9d98d4044f37dabce93086542e4db2512b1d4f051617d8835711`.
+
+**Übergabe / Grenzen:** Der bereits installierte alte Updater kann beim Einspielen dieser Reparatur einmalig weiter 500 ausgeben; anschließend `/admin/system` direkt öffnen und die angebotenen Migrationen abschließen. Genau dieser Weg ist mit dem Releasepaket geprüft. Kein Zugriff auf Produktionsprotokolle und keine Produktionsänderung durch diese Diagnose; Startseite und Anmeldung bei der Prüfung HTTP 200. Kein neuer Lighthouse- oder visueller Gesamtlauf. Die während der Arbeit extern geänderte `.claude/launch.json` bleibt unberührt und uncommitted.
