/* =============================================================================
   HexShield -- Tanitim sitesi tasarim sistemi (v3, "kurumsal")
   =============================================================================
   Tek dosya, tum tanitim sayfalarinda ortak.

   TEMA SOZLESMESI (panel ile ayni, bkz. hexsite.js):
     localStorage['hex_theme'] = 'dark' (varsayilan) | 'light'
     dark  -> html.dark-mode, body.dark-mode
     light -> sinif yok
   :root ACIK paleti tasir: JS tamamen kapaliysa sayfa okunabilir acik temada
   kalir (onyukleme betigi calismaz, .dark-mode eklenmez).

   TASARIM DILI ("kurumsal"): koyu LACIVERT-TURKUAZ zemin, TEK vurgu
   rengi (turkuaz), duz yuzeyler. Kaldirilanlar -- "sablon / yapay zeka" izleri:
   parlayan (glow) golgeler, gradyan metin, ikonlarin renkli kutu icindeki
   parlamasi, hap (pill) etiketler, hover'da yukari kayan kartlar, yuvarlak
   kose abartisi, bulaniklastirilmis ust serit, arka plan lekeleri. Yerine:
   dar yaricapli (4-8 px) koseler, ince 1 px cizgiler, buyuk ve agir basliklar,
   ust serit duz zemin, duyuru bandi, ikon seridi, ince ayiraclar.
   DIKKAT: renkler yalnizca BURADA tanimli. Sayfa dosyalarinda ham renk kodu
   yazmayin; tema degistiginde o parca geride kalir.
