/* ==========================================
   SLIDE ENHANCE — STRATUL 2
   Tranziții cinematografice între slide-uri:
   - Parallax zoom pe bg-img în timpul cortinei
   - Linie cupru care fulgeră la seam
   - Titlu cu reveal vertical mask
   - Contor slide (01 / 06)
   Hookuri: detectează tranziția prin clasele animating-in/out
   adăugate de JS_SiteMobila.js (nu-l modificăm).
