/* ── PANEL TECH-STACK TILT ─────────────────────────────────────────────────────
   Satu kartu besar berisi semua logo teknologi. Panel miring 3D sebagai satu
   bidang mengikuti kursor, dengan kilau (glare) yang bergerak.

   Menggantikan 16 kartu terpisah — masing-masing tilt sendiri terlihat
   terpecah dan "aneh". Satu panel = kesan tech-stack card yang kohesif.
