🔔 Countdown-Widget (ioBroker VIS + MagicMirror)

Dieses Widget zeigt automatisch die zwei nächsten anstehenden Countdowns an
(z. B. Weihnachten, Silvester, Urlaub, Touren usw.).

Abgelaufene Countdowns werden automatisch ausgeblendet.

⚠️ WICHTIGE HINWEISE (bitte lesen!)

JEDER Countdown muss im versteckten Subscribe-Block stehen

KEINE Einzeiler mit { ... } im JavaScript

Kein Array / kein Objekt-Literal

Code-Formatierung NICHT verändern

Sonst erscheint:

SyntaxError: Unexpected token 'null'

🧩 1. Subscribe-Block (Pflicht!)

Hier meldet VIS alle benötigten Datenpunkte an.

<div style="display:none;">
  {countdown.0.countdowns.Weihnachten.fullJson}
  {countdown.0.countdowns.Silvester.fullJson}
  {countdown.0.countdowns.SommerurlaubItalien.fullJson}
</div>


👉 Für jeden neuen Countdown MUSS hier eine Zeile ergänzt werden!

🖼️ 2. Anzeige-HTML (2 Slots)
<div style="text-align:center;">
  <div id="cd_text_xmas" style="font-size:28px;font-weight:700;line-height:1.15;">

  <div id="cd_text_ny" style="font-size:28px;font-weight:700;line-height:1.15;">

Die IDs bleiben absichtlich so – sie sind MagicMirror-erprobt.

➕ Neuen Countdown hinzufügen (Checkliste)
Beispiel: countdown.0.countdowns.Herbsturlaub.fullJson
✅ Schritt 1 – Subscribe-Block
{countdown.0.countdowns.Herbsturlaub.fullJson}

✅ Schritt 2 – OID definieren
const OID_4 = "countdown.0.countdowns.Herbsturlaub.fullJson";

✅ Schritt 3 – Renderfunktion ergänzen
if (i === 4) return renderGeneric(val, "Herbsturlaub", "🍂🧳");

✅ Schritt 4 – remainingSeconds / pickTwo erweitern

(analog zu Event 3)
