Druckdaten: Hintergrund-PDF (VDP) & eingebettete eigene Schriften

- Renderer auf FPDI (setasign/fpdi) umgestellt: Kunden-PDF wird als
  Seitenhintergrund importiert, nur dynamische Felder werden überlagert
  (Variable Data Printing); bei Hintergrund keine eigenen Schnittmarken
- Eigene Schriften (TTF/OTF) per TCPDF_FONTS::addTTFfont eingebettet,
  fontFamily pro Element; DejaVu-TTF im PHP-Image
- CardTemplate: backgroundPath + fonts; Renderer color() unterstützt {hex}
- CardAssetUploadController: Upload/Delete Hintergrund-PDF + Schrift-Upload,
  Speicher in var/storage/cards/{companyId} (außerhalb Webroot)
- Editor-GET liefert hasBackground + fonts
- Migration robust gegen MariaDB json_valid-CHECK (nullable -> '[]' -> NOT NULL)
- Konzept §13 ergänzt

Verifiziert: Kunden-Hintergrund + dynamische Felder + eingebettete Serifenschrift
+ QR; /FontFile im PDF.

 Gleiches `CardTemplate`-Modell mit `type = letterhead` und Format **A4**; der Renderer
 ist format-agnostisch (Maße + Elementliste). Bindings identisch + ggf. Adressfeld/Faltmarken.
+
+### Hintergrund-PDF (Variable Data Printing) & eigene Schriften
+
+**Hintergrund-PDF:** Der Kunde gestaltet die Karte vollständig in seinem DTP-Programm
+(InDesign/Illustrator: Logo, Farbflächen, Hintergrund, statische Texte) und exportiert
+ein druckfertiges PDF (CMYK, mit Beschnitt). Dieses wird hochgeladen und dient als
+**Hintergrund**; die Plattform legt darüber nur noch die **dynamischen Felder**
+(Name, Position, Kontakt, QR). Klassisches *Variable Data Printing*.
+
+- Technik: **FPDI** (`setasign/fpdi`) importiert die Seiten des Kunden-PDFs; der
+  Renderer (FPDI-Tcpdf) platziert sie als Seitenhintergrund (`useTemplate`) und
+  zeichnet die dynamischen Elemente darüber.
+- Erwartung: Hintergrund-PDF hat die Maße Endformat + Beschnitt (`width+2·bleed` ×
+  `height+2·bleed`). Seite 1 = Vorderseite, optional Seite 2 = Rückseite.
+- Bei Hintergrund-PDF: **keine** eigenen Schnittmarken/Beschnitt-Logik (der Kunde
+  liefert das); Element-Koordinaten weiterhin im Trim-Raum, Offset = `bleedMm`.
+- Die Vorlage enthält dann nur noch dynamische Elemente (Felder/QR), die statischen
+  entfallen.
+
+**Eigene Schriften:** TTF/OTF werden hochgeladen und per `TCPDF_FONTS::addTTFfont()`
+**eingebettet** (Subset). `CardTemplate` führt eine Schriften-Liste (`family → Pfad`);
+Elemente referenzieren eine `fontFamily` (Custom oder Core helvetica/times/courier).
+Font-Embedding ist zugleich Voraussetzung für striktes **PDF/X**.
+
+**Uploads/Datenmodell:** `CardTemplate.backgroundPath` (Pfad zum Kunden-PDF, nullable),
+`CardTemplate.fonts` (`[{family, path}]`). Dateien liegen außerhalb des Webroots unter
+`var/storage/cards/{companyId}/`. Upload-Endpunkte:
+`POST /api/companies/{id}/card-template/background` (PDF) und `.../font` (TTF/OTF).
