The inactive Plan/Fly button used to sit inset by the header's own padding on all sides, leaving a visible strip of the header tint around it instead of filling the header exactly like the HTML prototype. CSS solves this with a negative margin, which Flutter's Padding widget rejects (padding.isNonNegative assertion) - restructured so only the active button stays wrapped in the inset padding, while the inactive one is a raw Row child that naturally touches the header container's true top/bottom/outer edges and gets clipped to its rounded corner. Also adds a short gradient from the header's own tint into the button's solid color at the seam, softening what used to be a hard color edge.
