/* ============================================================================
   LevelEnAI — Design System · "Okyanus + Turkuaz"
   ----------------------------------------------------------------------------
   İlkeler
   1. Tek zemin, tek mürekkep, tek marka rengi. Renk süs değil, sinyal.
   2. Ekran başına tek doygun an (feature hero). Gerisi yüzey + saç teli + mürekkep.
   3. Derinlik renkli parıltıdan değil, kenarlıktan ve nötr gölgeden gelir.
   4. Hareket kullanıcıya cevap verir; hiçbir şey sonsuza kadar dönmez.
   5. Metin için kullanılan her renk çifti WCAG AA'yı geçer.

   Tema
   Tüm renkler anlamsal token üzerinden okunur; koyu tema yalnızca bu
   tokenları yeniden tanımlar. Bileşen kuralları iki temada da aynıdır.
   `data-theme` özniteliği kullanıcının açık tercihidir ve sistem tercihini ezer.
