   Visual language follows Fluent 2: communication blue as the single
   accent, Fluent neutral ramp, Segoe UI Variable, small radii (2/4/8) and
   Fluent's deliberately subtle elevation. No gradients on text or
   surfaces, no glows, no decorative texture — structure comes from
   hairline rules and spacing.
