 * Bilenyum site.css — paylaşılan chrome + component stilleri

 *   <link rel="stylesheet" href="assets/site.css">
 *   <style>...</style>   ← sayfa-özel stiller en sonda, override edebilir
 *
 * Akış sayfaları (giris, checkout, onboarding, dashboard, sifre-*) bu
 * dosyayı çekmez; kendi minimal layout'larını korur.
 *
 * Kanonik değerler:
 *   h2.title    → 38px
 *   .sec-inner  → padding: 80px 32px
 * Bunlardan saparmak isteyen sayfa kendi inline `<style>` bloğunda
 * override eder (cascade burayı sonradan yener).
