   21. GRADIENT HEADERS (Module Colors) — Enhanced
   ------------------------------------------------------------
   F8 KOREKSI (2026-07-03, verifikasi lanjutan): Catatan sebelumnya di sini
   menyatakan !important "wajib" karena 12 template lain mendefinisikan ulang
   nama class yang sama. Setelah dicek PERSIS nama class per file (bukan
   cuma keberadaan prefix .bg-gradient-), ternyata:
   - templates/partials/header2.html memang collide nama (dark/marketing/
     project/cost/purchasing/logistik/finance/operational) TAPI terverifikasi
     0 referensi di manapun (dead code, sudah ditandai terpisah).
   - templates/hsse/induction/kiosk_display.html juga punya `.bg-gradient-dark`
     TAPI itu halaman <!DOCTYPE html> standalone (kiosk display) yang TIDAK
     PERNAH memuat design_system.css sama sekali -- beda dokumen, beda cascade,
     tidak ada konflik runtime meski nama class sama.
   - 8 template lain (profile/index.html, finance/dashboard2.html,
     finance/fixed_asset_list.html, task_board/*, costcontrol/*, ahs/ahs_list.html)
     memakai nama BERBEDA (.bg-gradient-primary/-danger/-info/-success) yang
     TIDAK PERNAH ada di sini sama sekali -- sama sekali bukan collision.
   Kesimpulan: 0 collision nyata di runtime. !important DIHAPUS di 13 rule
   di bawah -- aman, terverifikasi, bukan asumsi. */

/* ------------------------------------------------------------
   F8-LANJUTAN (Opsi 1 dipilih user): Token semantik generik untuk KPI/
   dashboard card, KONSEP BERBEDA dari 13 token modul di atas (module
   identity vs status semantik Bootstrap-style). Sebelumnya didefinisikan
   ULANG di 8 template (Keluarga A/B/C/D, 4 varian sudut & warna berbeda
   — lihat histori diskusi audit). User memilih Keluarga A (135deg,
   slate→biru) sebagai token resmi tunggal.
   .bg-gradient-primary & .bg-gradient-danger & .bg-gradient-info: nilai
   PERSIS diambil dari templates/finance/dashboard2.html (satu-satunya
   anggota Keluarga A yang mendefinisikan ketiganya).
   .bg-gradient-success: TIDAK PERNAH ada di Keluarga A manapun (hanya di
   Keluarga B/C yang tidak dipilih) -- nilai di bawah adalah pilihan baru
   saya yang konsisten dengan pola 135deg + gelap→terang milik Keluarga A,
   memakai pasangan warna yang sama dengan .bg-gradient-cost di atas.
   Jika Anda punya preferensi warna sukses yang berbeda, ganti di sini saja
   (satu tempat) -- itulah gunanya konsolidasi ini. */
