/* 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 ~85% longtask halaman ini (terukur).
   Kini tinggi bar tetap 13px dan yang dianimasikan hanya transform:
   scaleY (0,23 = 3px/13px s.d. 1 = 13px) + opacity — properti kompositor,
   tampilan akhir identik (bar tumbuh dari alas, 3px -> 13px). */
