/*
 * #Bullaunch Trading Contest, halaman season. Design read: soft-launch kompetisi untuk trader ritel Indonesia yang datang dari iklan Meta di HP,
 * bahasa visual "dark luxury night trading" dari brand/BRAND-DNA.md, dial ENERGY 3 / RHYTHM 2 / MOTION 2.
 * Alasan utama:
 * - Gelap karena aturan brand (logo hanya di atas Night #0C0A08), bukan karena "terlihat tech".
 * - Gold hanya untuk angka uang, tombol, dan nomor kursi: angka adalah alasan orang datang.
 * - Cormorant Garamond untuk judul dan angka (suara brand), Instrument Sans lebar 80% untuk "#BULLAUNCH" (pengganti Barlow di logo SVG).
 * - Motif: "kursi" bernomor. Lima kursi papan dan sebelas pemenang; kursi kosong ditampilkan apa adanya, itu FOMO yang jujur.
 * - Satu cahaya hangat di belakang tiga host: titik fokus hero. Tanpa grid, orb, atau glass di banyak elemen.
