/* ===========================================================================
   NSMC GmbH — Stylesheet (v5) — „Editorial, ruhig & großzügig"
   ---------------------------------------------------------------------------
   ORGANISATIONSPRINZIP: Ruhe und Weißraum statt sichtbarer Struktur. Die Seite
   atmet — große Serifen-Headlines, vollflächige Fotos im menschlichen Maßstab
   als Bänder, großzügig gesetzte Textblöcke. Vertrauen durch Gelassenheit
   (Understatement-Linie von chisel), nicht durch technische Gitter.

   Abgrenzung der Gerüste:
   - v2 Leistungsverzeichnis (Nav oben, dichte Positionen)
   - v3 Phasenlauf (Nav links, Strang)
   - v4 Bento-Planblatt (Nav unten, 1px-Panel-Raster)  ← verworfen: zu verbaut
   - v5 Editorial (Nav oben transparent, vollflächige Bilder, viel Luft)

   Konkrete Bauteile aus den Referenzen (referenzen/*):
   - chisel → vollflächiges Foto-Hero mit Headline unten links; farb-adaptive Nav
     (Textfarbe folgt dem Hintergrund); alternierende, asymmetrische Bildblöcke;
     viewport-breiter Abschluss-Claim; Editorial-Serif + Grotesk.
   - enerblock → dezente Nummerierung „01 /" der Leistungen.

   Farbe: das gewünschte Blau, aber luftig — Navy-Text, ein Azur-Akzent,
   sehr helles kühles Papier. Bilder im Blau-Duoton nur im Hero/Band.
