/* Perbaikan Kehalusan Bagian E: keyframes dulu menganimasikan `height`
   (properti layout) -> animasi berjalan di main thread dan memaksa
   style+layout+paint pada SETIAP frame selama musik hidup; di bawah
   throttle CPU 4x itulah sumber beban longtask halaman ini.
   Kini tinggi bar tetap 13px dan yang dianimasikan hanya transform:
   scaleY (0.2308 = 3px/13px s.d. 1 = 13px) + opacity — properti kompositor,
   tampilan akhir identik (bar tumbuh dari alas, 3px -> 13px).
   Tinggi jeda tetap 4px via transform: scaleY(0.3077) (= 4/13) pada
   aturan dasar .eq-musik-v3 i di atas. */
