FIX-NETATMO-05: ACeP Native-Farben + bessere Spalten-Verhaeltnisse

* Farben auf ACeP 7-Farben-Palette gemappt: BLACK, WHITE, GREEN, BLUE, RED, YELLOW, ORANGE
  (PIL.quantize dithert sonst alles in matschige Mischfarben)
* Background PAPER_BG = (255,255,255) echtes Weiss statt warm-creme
* Spalten-Verhaeltnis neu: Indoor 32% (mehr Platz fuer 5 Sensoren),
  Aussen 28%, Mitte 18%, Forecast 22%
* Big-Temp candidates von [150,130,110,95] auf [120,100,85,72,60] reduziert
* FAINT und INK_LIGHT als BLACK definiert (Grautöne ergeben Mischpixel)
* Funktioniert mit echten Daten: zeigt 5 Indoor-Sensoren + alle Aussensensoren

+# Netatmo Weather Station Plugin
+
+Zeigt die Live-Daten deiner heimischen [Netatmo Wetterstation](https://www.netatmo.com/de-de/weather/weatherstation)
+auf dem 7.3″ ACeP Dashboard: Indoor-Temperatur, CO₂, Luftfeuchte, Luftdruck,
+Outdoor-Werte, Wind (Stärke + Böen + Richtung mit Windrose) und Regenmengen.
+
+Funktioniert mit **jeder** Netatmo-Konfiguration (Hauptmodul + beliebige
+Zusatzmodule). Module, die du nicht hast, werden automatisch weggelassen.
+
+![Netatmo 4×4](docs/netatmo_4x4.png)
+
+---
+
+## 1. Netatmo-App registrieren
+
+Damit das Plugin Daten abrufen darf, brauchst du eine App-Registrierung
+bei Netatmo. Das ist einmalig und kostenlos.
+
+1. Gehe zu <https://dev.netatmo.com/apps/> und logge dich mit deinem
+   Netatmo-Account ein.
+2. Klicke **Create an App**.
+3. Fülle das Formular aus:
+   - **Name**: z. B. „epaper-dashboard"
+   - **Description**: z. B. „Wetterdaten auf meinem ePaper-Display"
+   - **Data Protection Officer**: nicht erforderlich für eine persönliche App
+4. Bei den **Scopes** wähle mindestens **`read_station`** aus
+   (Standard-Scope der Weather API). Mehr brauchst du für dieses Plugin nicht.
+5. Speichern. Du bekommst **Client-ID** und **Client-Secret** angezeigt —
+   die brauchst du gleich.
+
+> Hinweis: Netatmo verwendet **OAuth2 mit Password-Grant** für die
+> Weather API (kein Browser-Redirect nötig). Dein Passwort wird nur
+> lokal für den initialen Token verwendet — es wird **nie** auf der
+> Festplatte persistiert, sondern liegt nur im RAM des laufenden
+> Dashboard-Prozesses.
+
+---
+
+## 2. Plugin konfigurieren
+
+### Option A — über die Admin-Weboberfläche (empfohlen)
+
+`http://<pi>:8080/` öffnen, in der Sidebar das Widget **Netatmo**
+auswählen und die Werte eintragen:
+
+| Feld | Wert |
+|---|---|
+| Client-ID | von dev.netatmo.com/apps |
+| Client-Secret | von dev.netatmo.com/apps |
+| Username | deine Netatmo-Login-E-Mail |
+| Password | dein Netatmo-Passwort |
+| Station (Filter) | leer lassen, wenn du nur eine Station hast |
+
+Speichern. Klicke **Refresh Now** — wenn alles passt, sollten nach
+~30s die ersten Daten erscheinen.
+
+### Option B — direkt in `config.json`
+
+Unter `plugin_configs.netatmo` eintragen (Beispiel siehe
+[`config.netatmo.example.json`](config.netatmo.example.json)):
+
+```json
+{
+  "plugin_configs": {
+    "netatmo": {
+      "client_id":     "abc123...",
+      "client_secret": "def456...",
+      "username":      "du@example.com",
+      "password":      "GEHEIM",
+      "station_filter": "",
+      "show_indoor":   true,
+      "show_outdoor":  true,
+      "show_wind":     true,
+      "show_rain":     true,
+      "show_compass":  true,
+      "show_secondary": true,
+      "co2_thresholds": "ok@600,warn@1000,alert@1500",
+      "bar_gradient":   true,
+      "temp_unit":      "C",
+      "wind_unit":      "kmh"
+    }
+  }
+}
+```
+
+> ⚠️ Secrets in `config.json` sind auf dem Pi persistent (lokal in
+> `/home/<user>/.hermes/projects/pi/config.json`). Wenn du das
+> vermeiden willst, nimm die Admin-UI — die legt sie genauso ab, aber
+> du siehst die Werte nie im Klartext-Editor.
+
+---
+
+## 3. Layout zuweisen
+
+In der Admin-UI ein Netatmo-Widget auf das Grid ziehen. Das Plugin ist
+**responsive**: dieselbe Konfiguration sieht auf jedem Slot gut aus.
+
+| Slot | Was du siehst |
+|---|---|
+| **1×1** | Große Außen-Temperatur, Mini-CO₂/Feuchte-Status |
+| **2×1** | Outdoor-Temperatur + Wind-Geschwindigkeit kompakt |
+| **4×1** | Indoor · Outdoor · Wind/Regen — drei Spalten |
+| **1×4** | Vertikale Liste aller Module |
+| **2×2** | Indoor-Card (mit CO₂-Bar) + Outdoor-Card + Wind/Regen-Bereich |
+| **4×4** | Volle Ansicht mit allen Modulen, Min/Max, Windrose |
+
+Das Plugin priorisiert bei der Layout-Wahl **wide/tall** vor `small`,
+damit 4×1- und 1×4-Slots nicht in die Mini-Ansicht fallen.
+
+---
+
+## 4. Optionen im Detail
+
+| Option | Typ | Default | Bedeutung |
+|---|---|---|---|
+| `client_id` | secret | — | Netatmo App Client-ID |
+| `client_secret` | secret | — | Netatmo App Client-Secret |
+| `username` | secret | — | Netatmo Login (E-Mail) |
+| `password` | secret | — | Netatmo Passwort (nur RAM) |
+| `station_filter` | string | `""` | Substring-Filter auf Stations-/Modulname |
+| `show_indoor` | bool | `true` | Hauptmodul + zusätzliche Indoor-Sensoren anzeigen |
+| `show_outdoor` | bool | `true` | NAModule1 (Außen) anzeigen |
+| `show_wind` | bool | `true` | NAModule2 (Wind) anzeigen |
+| `show_rain` | bool | `true` | NAModule3 (Regen) anzeigen |
+| `show_compass` | bool | `true` | Windrose in der Wind-Card zeichnen |
+| `show_secondary` | bool | `true` | Min/Max + letzte Aktualisierung |
+| `co2_thresholds` | string | `ok@600,warn@1000,alert@1500` | CO₂-Bar Schwellen (ppm) |
+| `bar_gradient` | bool | `true` | Verlaufsmodus der Bar |
+| `temp_unit` | select | `C` | `C` oder `F` |
+| `wind_unit` | select | `kmh` | `kmh` oder `ms` |
+
+### CO₂-Schwellen anpassen
+
+`co2_thresholds` ist ein String im Format `farbe@ppm_in_ppm`.
+Mehrere Stufen durch Komma trennen:
+
+- `ok@600,warn@1000,alert@1500` — Netatmo-Default-Empfehlungen
+- `ok@800,warn@1200` — nur 2 Stufen (kompakt)
+- `ok@1000,warn@1500,alert@2000` — strenger (z. B. für Schlafzimmer)
+
+### Station-Filter
+
+Wenn du mehrere Stationen hast (z. B. „Home" und „Office"), kannst du
+über `station_filter` einen Substring matchen. Erst wird der
+Stationsname geprüft, dann die Modulnamen. Leer = erste Station.
+
+---
+
+## 5. Fehlerdiagnose
+
+### Auth-Fehler (HTTP 401)
+
+- Stimmen Client-ID/Secret mit dem Eintrag auf dev.netatmo.com/apps überein?
+- Stimmt das Passwort (case-sensitive)?
+- Wurde deine App bei Netatmo evtl. deaktiviert?
+
+→ Plugin setzt den Token-Cache automatisch zurück, beim nächsten Render
+wird ein neuer Token geholt.
+
+### "Keine Station gefunden"
+
+- Hat deine Station in den letzten 4h Daten an Netatmo geschickt?
+  (Netatmo markiert sie sonst als offline.)
+- Stimmt der `station_filter`? Wenn du dort z. B. „Home" eingibst, aber
+  die Station heißt „Home Office", passt es trotzdem (Substring-Match).
+  Leer = erste Station.
+
+### "API nicht erreichbar"
+
+- Pi hat Internet? (`ping api.netatmo.net`)
+- DNS? (`nslookup api.netatmo.net`)
+
+### Werte fehlen / sind 0
+
+- Manche Datenpunkte sind nur in der **Paid**-Subscription verfügbar
+  (z. B. Historische Daten > 1h). Aktuelle Werte sind immer frei.
+
+---
+
+## 6. Technische Details
+
+| Aspekt | Wert |
+|---|---|
+| API-Version | Netatmo Connect OAuth2 |
+| Endpoints | `POST /oauth2/token`, `GET /api/getstationsdata` |
+| Token-Lebensdauer | 10800s (3h), Refresh on the fly |
+| Cache | In-Memory, kein Disk-IO pro Render |
+| Datenquelle | Netatmo Cloud (Update alle ~10 Min) |
+| Modul-Typen | NAMain, NAModule1..4 |
+| `reachable`-Feld | „true" wenn das Modul in den letzten 4h gesehen wurde |
+
+### Was wird pro Refresh gemacht?
+
+1. Prüfe Token-Cache (RAM). Wenn abgelaufen oder fehlend → hole neuen
+   Token via Password-Grant (initial) oder Refresh-Grant.
+2. `GET /api/getstationsdata?get_favorites=false` mit Bearer-Token.
+3. Parse Antwort, filtere nach `station_filter` und sichtbaren Modulen.
+4. Rendere je nach Slot-Größe (`small` / `wide` / `tall` / `standard`).
+
+Bei 401 wird der Token-Cache geleert und **einmal** neu authentifiziert.
+Wenn das auch fehlschlägt → roter Error-Banner mit der genauen HTTP-Meldung.

+"""DesignBase — Plugin Design Template / Schablone.
+
+Dieses Modul ist KEIN eigenständiges Widget, sondern eine SAMMLUNG
+von Design-Konzepten, Layout-Helfern und Theme-Definitionen,
+die als Vorlage für alle anderen Plugin-Renderer dienen.
+
+ANATOMIE EINES DESIGN-TEMPLATES
+=================================
+
+Jedes Plugin-render() folgt diesem Schema:
+
+    def render(self, draw, fonts, x, y, w, h):
+        theme   = self._theme()          # Theme-Objekt mit Farben + Schriften
+        data    = self.fetch()            # Daten holen
+        if "_error" in data:
+            render_error_banner(...)
+            return
+        layout  = self._pick_layout(w, h)  # Layout-Strategie wählen
+        self._render_header(draw, theme, x, y, w, header_h)
+        self._render_body(draw, theme, data, x, body_y, w, body_h, layout)
+        if self._show_footer(w, h):
+            self._render_footer(draw, theme, data, x, y+h-footer_h, w, footer_h)
+
+Die 4 LAYOUT-STRATEGIEN
+========================
+
+  is_small  (1x1):     Eine einzige große Zahl / ein Icon
+  is_wide   (4x1/2x1): Horizontale Teilung in 2-3 Spalten
+  is_tall   (1x4/1x2): Vertikale Teilung in Zeilen
+  standard  (2x2+):     Header + Content + Footer (oder Karten)
+
+Die 4 THEMES
+=============
+
+  THEME_LIGHT  — Weiß, schwarz, eine Akzentfarbe (z.B. Netatmo: blau)
+  THEME_DARK   — Fast schwarz, helle Farben auf dunklem Grund
+  THEME_RETRO  — Gelb/Orange-Schwarz (80er-Terminal-Feeling)
+  THEME_MAG    — Minimal, typografisch, viel Weißraum
+
+Farben werden IMMER über theme.xxx bezogen, NIEMALS direkt als RGB-Tuple.
+Das erlaubt komplettes Umstyling ohne den Renderer-Code anzufassen.
+
+Farben-Schema pro Theme (Palette: FG, BG, ACCENT, OK, WARN, ALERT, INFO):
+
+  THEME_LIGHT:  BG=WHITE, FG=BLACK, ACCENT=BLUE,  OK=GREEN, WARN=YELLOW, ALERT=RED
+  THEME_DARK:   BG=BLACK, FG=WHITE, ACCENT=CYAN,  OK=GREEN, WARN=ORANGE,ALERT=RED
+  THEME_RETRO:  BG=BLACK, FG=YELLOW,ACCENT=ORANGE, OK=GREEN, WARN=YELLOW, ALERT=RED
+  THEME_MAG:    BG=WHITE, FG=BLACK, ACCENT=ORANGE, OK=GREEN, WARN=ORANGE, ALERT=BLUE
+
+Beispiel-Implementierung: widgets/netatmo.py (theme='light', accent='blue')
+Beispiel-Implementierung: widgets/weather.py (theme='light', accent='orange')
+Beispiel-Implementierung: widgets/system.py  (theme='light', accent='green')
