  Alina Security operator portal -- design tokens and shell.

  Direction: a calm operations handover board. Warm paper, deep ink,
  restrained green; amber and red are reserved for attention only, and never
  used alone -- every status also carries a text label or glyph.

  Signature element: the Duty Line, a live Singapore-time handover sequence
  through today's briefing, acknowledgement, start and completion milestones,
  grouped as Earlier / Now / Next / Later at every width.
