   Four separated PNG layers (80g text / hand / phone / cooler) stacked

   fill drops against the dark section background — only the white

   (RGB ring intact) because it's the visual hero.

   How to MOVE it:
     • right: ← زِدها لتحريك الكيبل يساراً / أنقصها لتحريكه يميناً
     • top:   ← زِدها لإنزاله / أنقصها لرفعه
     • width: ← غيّر الحجم (الارتفاع يحسب تلقائياً من الصورة)

   How to CHANGE its COLOUR:
     • افتح index.html وابحث عن `<filter id="cableTint">`
     • بدّل الأرقام الثلاثة (0.36 / 0.88 / 1.00) — وهي R/G/B بنسبة 0-1
       (مثلاً: للأحمر → 1 / 0.2 / 0.2 ، للأبيض → 1 / 1 / 1)

   How to CHANGE the GLOW colour:
     • عدّل قيم rgba داخل `drop-shadow(...)` أدناه

   لماذا هذا الأسلوب؟ ⟶  `<img>` + SVG filter يعمل على file:// أيضاً.
