/*
  CARA MENAMBAH WARNA IKON CUSTOM:
  ─────────────────────────────────
  1. Salin salah satu blok di atas
  2. Ganti ".nama-icon" dengan nama kelas baru (misal: .react-icon)
  3. Ganti background: rgba(R,G,B,0.15) — pilih warna brand software tersebut
     (cari hex color brand di: https://brandcolors.net)
  4. Ganti color: #HEX dengan warna utama brand tersebut
  5. Di HTML, gunakan class baru di <div class="skill-icon react-icon">
