   ERP KONSTRUKSI — DESIGN SYSTEM
   Arah visual: "blueprint proyek" — navy gelap + garis teknis halus,
   ditemani aksen oranye safety-cone, dan tipografi teknis (Space
   Grotesk untuk judul, IBM Plex Sans untuk isi, IBM Plex Mono untuk
   angka/kode supaya kolom kuantitas & harga rapi sejajar).
   Semua font & Chart.js di-vendor lokal (assets/fonts, assets/vendor)
   supaya aplikasi tetap jalan tanpa koneksi internet saat demo.
