Visual audit found several issues in the navbar / header layer; this pass
addresses the cluster.
- AuthBar: localize sign in/out + dev-disabled message; switch matrix-green
(#00ff9c) to gold (#e0c080) to match the magazine palette.
- NavLink (new): client component reading usePathname to mark the active
section with aria-current="page" and a gold underline+fill, so the user
knows where they are inside the entity hub.
- Locale toggle: bump font to 12px, widen the pill, lift the active state's
contrast. Hard reload on switch (window.location.reload) instead of
router.refresh — that is what makes the <title>, <html lang> and og:locale
actually update on toggle (router.refresh kept stale layout metadata).
- Root layout: convert static `export const metadata` to generateMetadata()
so title/description/OG/twitter all read the cookie per request. Drop the
duplicate floating LocaleToggle at bottom-left; the navbar carries it now.
- BureauNav: drop the cyan-on-home / gold-on-bureau split (palette mismatch
with SiteHeader); single gold tone; localize "home"/"case files" + aria
labels; mount AuthBar inside the bar so sub-pages get a sign-in surface.
- Pages using BureauNav: drop the standalone <AuthBar /> below it (now
duplicated). Affected: /bureau, /c/[slug], /h/[hypothesisId], /jobs/[id].
- Lift nav-link rest text from #9aa6b8 to #cbd2dd for WCAG-AA on near-black.
Verified live: title/lang/og:locale switch with cookie; active link gold
indicator on /sightings; "Entrar"/"Sign in" localizes; no double AuthBar.
