- Drop max-w-[1280px] on the desktop header inner row so the header
expands with wider viewports instead of staying capped.
- Move the inline nav / burger toggle from min-[1000px] to xl (1280px)
so the nav only appears when all six items have enough room. The old
threshold relied on overflow-x-auto, which clipped the first/last
characters ("ll assets", "Popula").
- Remove the now-unused .header-nav-scroll CSS along with the scroll
fallback wiring on the nav element.
Mid-width viewports (1000–1280px) now show the burger drawer instead
of a horizontally-scrolled nav. main content stays at max-w-[1280px]
on purpose.
