/*
 * OfferMed — statik yasal site (offermed.selhux.com)
 *
 * Tek stil dosyası, beş sayfa (TR/EN landing + iki belgenin iki dili). JavaScript
 * yok ve olmayacak: nginx.conf'taki Content-Security-Policy `default-src 'none'`
 * ile başlıyor, yani bir script etiketi eklenirse tarayıcı onu ENGELLER. Aynı
 * politika dış yazı tiplerini ve analytics'i de kapatır — gizlilik metninin
 * "bu site sizi izlemez" cümlesi böylece bir iddia değil, uygulanan bir kural.
 *
 * Renkler mobil uygulamanın `src/constants/theme.ts` paletinden alındı; site ile
 * uygulama aynı markayı göstersin diye birebir aynı onaltılıklar kullanıldı.
