/* =============================================================================
   PortfolyoMaker — Design System (V2 · Faz 1)
   -----------------------------------------------------------------------------
   Amaç: Tüm yeni frontend'in üzerine kurulacağı tek, merkezi tasarım sistemi.
   Kural: BU DOSYA KATMALIDIR (additive). Mevcut legacy token/class'ları
          (site.css içindeki --pm-ink, .pm-btn-primary, .pm-card ...) EZMEZ.
          Yeni her şey `pm-` + BEM konvansiyonundadır (ör. .pm-btn--primary).
   Namespace: pm-  (sk-portfolyom- ve hm- kademeli olarak buraya taşınacaktır)
   Not: Renkler semantic token'lar üzerinden verilir → ileride Dark Mode için
        [data-pm-theme="dark"] bloğu token'ları yeniden eşler.
