/* mail.css — BMC Mail dashboard, amber Terminal aesthetic.
   Ports admin.css's SHELL patterns (sidebar, topbar, kpi, table-card) onto
   shared.css tokens. Does NOT import admin.css (coupled to admin's #app global
   state). Reuses shared.css directly for: badges, buttons, inputs, .empty,
   .loading-screen, .saving-indicator, .error-bar, and the animation keyframes
   (fadeUp / rowFadeIn). Sharp 2px radii throughout = Terminal feel. */
