/* =============================================================
   Tujuan: stylesheet utama RathurMail, termasuk landing, inbox, login,
   dan halaman /domains dengan responsive mobile yang tidak tabrakan.
   Dipakai oleh: views/layout.ejs, views/index.ejs, views/domains.ejs,
   views/admin.ejs, dan route web Express.
   Dependensi utama: CSS custom properties, Font Awesome class icon,
   markup EJS di folder views.
   Fungsi public/utama: layout app shell, form, toolbar, DNS table,
   domain list, toast, dan responsive <=640px.
   Side effect penting: hanya mengatur tampilan browser; tidak melakukan
   DB read/write, HTTP call, atau file I/O.
   RathurMail v1.0 — Premium UI
   Adopted from mehmetkahya0/temp-mail v4.0 style
