/* ---------- Yazı tipleri: KENDİ SUNUCUMUZDAN (self-host) ----------
 * 15-1a düzeltmesi (K7): Google Fonts'tan çekmek Türkçe metinle birlikte
 * latin + latin-ext alt kümelerini AYRI AYRI indirtiyordu (8 woff2 → 16 istek).
 * Burada her ağırlık için latin + latin-ext TEK dosyada birleştirildi:
 *   Inter (değişken 400-500) · Space Grotesk (değişken 500-700) · IBM Plex Mono 400/500
 * → 4 istek, üçüncü taraf isteği YOK (CSP `font-src 'self'`, gizlilik metni daha da doğru).
 * Dosyalar OFL lisanslı, google/fonts kaynaklarından fonttools ile türetildi;
 * ayrıntı + lisans metinleri: /fonts/OFL.txt · karar: docs/DECISIONS.md (KARAR 39).
 * `unicode-range`: yalnız latin + latin-ext (kiril/yunan/vietnamca hiç indirilmez).
 * Dosya adları sürümlü (`-v1`) → /fonts/** uzun süreli immutable önbellek.
