/* Sarda Magnets Group: design preview v3.
   Owner brief: Apple-inspired treatment. Charcoal, brushed steel, warm
   white, with Sarda red and navy as restrained accents.
   Design read: B2B industrial catalogue for engineers and buyers.
   Dials: ENERGY 2 / RHYTHM 2 / MOTION 1.
   Reasons:
   - warm white #F6F5F1 ground: softer than pure white, keeps product
     cut-outs (shot on white) reading as objects on cards.
   - charcoal #1D1D1F ink and primary buttons: neutral authority; colour is
     saved for the one action that matters (Request a Quote, Sarda red).
   - brushed steel gradient: used only on the model finder and quote list
     surfaces, the material Sarda products are made of.
   - navy #202868 (logo) for small labels and the pole motif only.
   - fewer borders: separation comes from white cards on warm ground. */
