/* ==========================================================================
   Regal Systems LLC — Site Stylesheet
   Concept: "Engineered Authority" — regal confidence, engineered precision.
   Deep ink navy + warm paper + brushed bronze, hairline blueprint grid,
   a bold Caslon display face against a plain institutional sans, with a
   mono "systems" label voice for eyebrows, nav, and form labels.
   No rounded corners anywhere by design. No numbered badges either —
   sequence is carried by plain hairlines and small square bronze marks.
