   GB1 Ingenieure GmbH — Corporate Design
   Prinzip: ruhig, luftig, viel Weißraum. Farbe sparsam als Akzent.
   Statt Schatten: dezenter Flat-3D-Kantenstil (Zitat der Logo-Balken).

   Farbwelt aus dem Logo:
     Petrol   #23869a   (Akzent- und Interaktionsfarbe)
     Ziegel   #a23026   (nur für primäre Call-to-Actions)
     Tinte    #1d1d1b   (Text)
     Grau     #706f6f   (Sekundärtext)
   Flächen: neutrale helle Grautöne (kein Farbtint).
   Schrift: Open Sans (lokal eingebunden, keine Google Fonts)
   ========================================================================== */

/* --------------------------------------------------------------------------
   1. Fonts — Open Sans Variable (wght 300–800, wdth 75–100), lokal eingebunden
   Typo-Prinzip wie im Logo (Regular + Light): Mengensatz schwarz in wght 350,
   Grauwirkung über das Schriftgewicht statt über graue Textfarbe.

   font-display: optional (statt swap/fallback) + <link rel="preload"> in
   header.php: kein sichtbares Umspringen der Schrift beim (Neu-)Laden. Der
   Font wird entweder rechtzeitig aus dem Cache genutzt oder für diesen
   Seitenaufruf gar nicht erst nachträglich eingewechselt — kombiniert mit
   langem Cache (siehe dev-router.php) ist die Schrift ab dem zweiten
   Seitenaufruf immer sofort da.
