Header bar is #1D4ED8 but logo was rendering with navy text on the tile's #2563EB→#1E3A8A gradient — wordmark + tagline were nearly invisible. Flip all three header breakpoints to variant="onDark" (white wordmark, slate-200 tagline). Also: switch the onDark tagline accent rule from #1D4ED8 (same blue, invisible) to #7DD3FC cyan, and paint a faint white ring around the tile so the rounded mark stays distinct from the header background.
