+## Outage: PocketBase unreachable
+
+If `eb-pocketbase` is down while `eb-blazor` runs, the app does not render
+half-empty pages (the menu comes from PocketBase too). A gate in `Program.cs`
+answers every **page** request with the static `wwwroot/maintenance.html`:
+
+| Request | Answer while PocketBase is down |
+|---|---|
+| Any page (`/`, `/board`, `/posts/…`, unknown slugs) | **503**, `Retry-After: 60`, maintenance page |
+| `/health` | **503** `PocketBase unreachable` (for Uptime Kuma) |
+| `/events.ics` | 200 with an empty calendar, so subscriptions keep working |
+| `/events/{id}.ics` | 503 |
+| Static files (CSS, fonts, PDFs, `/maintenance.html`) | served as usual |
+
+The gate caches the health check for **10 seconds** (`PocketBaseHealthCache`). So
+after PocketBase stops, pages can render for up to 10 s more (the components
+degrade on their own in that window: empty menu, a short note, 503), and after it
+starts again the maintenance page can stay up for up to 10 s. No restart of the
+web app is needed — the site comes back by itself.
+
+`maintenance.html` carries its styles inline, as a copy of the tokens from
+`app.css`. When colours change there, copy them over.

+## Gestaltungsbausteine
+
+Alle Texte (`body` von Seiten und Beiträgen, `intro` und `answer` bei den FAQs)
+sind **Markdown**. Die Website gestaltet sie automatisch: Zwischenüberschriften
+(`## …`) bekommen einen grünen Strich, Listen grüne Punkte, Zitate (`> …`) einen
+farbigen Balken. Darüber hinaus gibt es ein paar **Bausteine**, mit denen du eine
+Seite selbst gestaltest — ohne Code und ohne HTML.
+
+> **Kein HTML.** HTML im Text (`<div>`, `<br>`, `<script>` …) wird nicht
+> ausgeführt, sondern als Text angezeigt. Das ist Absicht: Die Datenschutzerklärung
+> sagt zu, dass kein Programmcode im Browser läuft. Für Gestaltung die Bausteine
+> unten nehmen.
+
+### Bausteine mit `:::`
+
+Ein Baustein beginnt mit `::: name` in einer eigenen Zeile und endet mit `:::`.
+Dazwischen steht normales Markdown. Vor und nach dem Baustein eine Leerzeile
+lassen. Die Namen sind fest; ein **vertippter Name** schadet nicht — der Inhalt
+erscheint dann einfach als normaler Text.
+
+**Kennzahlen** — eine Liste wird zu großen Zahlen-Kacheln. Der **fett**
+geschriebene Anfang ist die Zahl, der Rest die Beschriftung darunter:
+
+```markdown
+::: kennzahlen
+- **seit 1975** im Einsatz für die IGMH
+- **über 500** Mitglieder
+- **ab 10 €** Jahresbeitrag
+:::
+```
+
+**Aufruf** — eine hervorgehobene Box für die wichtigste Aktion der Seite. Links
+darin erscheinen als Button:
+
+```markdown
+::: aufruf
+Die Beitrittserklärung füllen Sie online beim Förderverein aus.
+
+[Zur Beitrittserklärung](https://easyverein.com/public/FDI/applicationform/21612)
+:::
+```
+
+**Kacheln** — eine Liste als Raster aus Karten. Ein **fetter** Anfang wird zur
+Überschrift der Karte:
+
+```markdown
+::: kacheln
+- **Pädagogik** Bessere Rahmenbedingungen für die Arbeit an der Schule
+- **Projekte** Musische, sportliche und kulturelle Vorhaben
+- **Ausstattung** Anschaffungen, die allen zugutekommen
+:::
+```
+
+**Team** — eine Personenliste wird zu Karten mit Initialen-Kreis. Jeder
+Listenpunkt ist eine Person:
+
+```markdown
+## Vorsitz
+
+::: team gross
+- **Maik Palm** (Vorsitzender)  
+  *Schulkonferenz, Mensarat, Homepage*  
+  Mitglied im Gesamtelternbeirat und im Schulbeirat der Stadt Mannheim.
+- **Gentiana Erol** (1. Stellvertreterin)  
+  *Schulkonferenz, Kommunikation Hausmeister, Mensarat*
+:::
+
+## Beisitz
+
+::: team
+- **Isabell Vesper**
+- **Susanne Naumburg**  
+  *Stellvertretende Schulkonferenz*
+:::
+```
+
+- Der **fette Name** am Anfang wird die Überschrift der Karte, die **Rolle in
+  Klammern** dahinter ein farbiges Etikett. Beides außer dem Namen ist optional.
+- Die **kursive** zweite Zeile sind die Zuständigkeiten, durch Komma getrennt;
+  jede wird ein kleines Schildchen.
+- Jede **weitere Zeile** erscheint als kleiner Text darunter (Links gehen).
+- Zeilenumbruch innerhalb einer Person: zwei Leerzeichen am Zeilenende, die
+  Folgezeilen mit zwei Leerzeichen einrücken (wie oben).
+- Initialen und Farbe des Kreises entstehen **automatisch aus dem Namen**; es gibt
+  bewusst keine Fotos (siehe `docs/recht.md`).
+- `::: team gross` ist für den Vorsitz gedacht: Die Karten bleiben gleich groß,
+  nur das Rollen-Etikett wird kräftig blau hervorgehoben. Ein vertipptes Wort
+  nach `team` schadet nicht: Die Etiketten erscheinen dann einfach normal.
+- Die Überschriften (`## Vorsitz`, `## Beisitz` …) stehen **außerhalb** der
+  Blöcke; jede Gruppe ist ein eigener `::: team`-Block.
+- Beginnt ein Listenpunkt nicht mit einem fetten Namen, wird er eine schlichte
+  Karte mit genau dem Text, der dasteht.
+
+**Hinweis** — eine dezente Info-Box mit Info-Symbol:
+
+```markdown
+::: hinweis
+Bei dringenden Angelegenheiten wenden Sie sich bitte direkt an das Sekretariat.
+:::
+```
+
+### Links, die sich automatisch verändern
+
+- **Links auf andere Websites** (`https://…`) bekommen ein kleines Pfeil-Symbol.
+  Links auf eigene Seiten schreibst du ohne Domain: `[Kontakt](/contact)`.
+- **PDF-Links** (Adresse endet auf `.pdf`) bekommen ein Datei-Symbol und den
+  Hinweis „PDF“. Steht der Link **allein** in einer Zeile oder einem
+  Listenpunkt, wird er zur Datei-Karte — so wird eine Liste von Dokumenten zum
+  Download-Bereich:
+
+  ```markdown
+  - [Aufnahmeantrag Förderverein](/dokumente/aufnahmeantrag-foerderverein.pdf)
+  - [Einzugsermächtigung](/dokumente/einzugsermaechtigung.pdf)
+  ```
+
+  Die PDF-Dateien selbst liegen nicht in PocketBase, sondern im Code unter
+  `wwwroot/dokumente/` (ein neues PDF braucht also einen Entwickler).
+- **E-Mail-Link allein in einem Absatz** wird zum Button:
+
+  ```markdown
+  [kontakt@elternbeirat-igmh.info](mailto:kontakt@elternbeirat-igmh.info)
+  ```
+
+  Steht der Link mitten im Satz („Schreiben Sie an …“), bleibt er ein normaler
+  Link.
+
+### Tabellen
+
+Tabellen gehen mit senkrechten Strichen; die zweite Zeile trennt die Kopfzeile
+ab. Auf dem Handy lässt sich eine breite Tabelle seitlich schieben.
+
+```markdown
+| Tag      | Uhrzeit   | Ort        |
+|----------|-----------|------------|
+| Dienstag | 19:00 Uhr | Hörsaal 2  |
+```
