Blog and contact (and about/pricing/legal) pages rendered a stripped-down
header (logo + auth buttons only) with no nav — the site nav "disappeared".
Extracted the landing header into a shared <SiteHeader> (logo, nav, theme
toggle, auth-aware actions, mobile menu) used on every public page for
consistent UX.
- new components/site-header.tsx (nav links work from any route via /#…)
- landing nav gains Blog + İletişim so all pages share the same 5-link nav
- about, contact, pricing, blog, blog/$slug, kvkk, privacy, terms → SiteHeader
- demo keeps its purpose-built demo header (sticky + theme + CTA)
typecheck + biome clean.
