/* ===========================================================================
   Portfolio Studio — public site styles
   One shared semantic layout (top nav → hero → stats → sections) skinned by 5
   themes, each an ORIGINAL design inspired by a reference portfolio:
     bold      — big type, dark            (sawad / majd vibe)
     terminal  — developer / monospace     (red1 AI-dev vibe)
     clean     — minimal light             (aaabadcode / toukoum vibe)
     editorial — serif & elegant           (majd editorial vibe)
     vibrant   — colorful designer         (aahanabobade vibe)
   Differences are driven by CSS variables + a few per-theme rules.
