/* ==========================================================================
   ERP HGK — Design Tokens
   Palette: deep indigo-navy sidebar (authority, trust) + warm off-white
   content canvas (data legibility) + teal accent (positive/financial action)
   + amber (pending/attention) + rose (overdue/negative).
   Type: Inter for UI text, IBM Plex Mono for all numeric/currency figures —
   monospaced digits let columns of money align visually, which matters a
   lot more in an ERP than in a marketing page.

   JS (enterApp()) sudah benar men-set loginScreen.hidden = true setelah
   login berhasil, tapi tanpa baris ini, aturan "display: flex" di atas
   MENIMPA perilaku bawaan browser untuk atribut [hidden] (yang
   seharusnya otomatis jadi display:none) — akibatnya layar login tetap
   menimpa aplikasi secara visual walau secara teknis sudah "hidden".
   Kemungkinan tidak pernah kelihatan sebelumnya karena kebanyakan orang
   jarang logout-login ulang di tab yang sama. */
