   AccuraTrial Command Center — design system
   2026-08-24 "quiet shell" redesign (design_handoff_command_center_redesign).

   One page, one job, one primary action. A single amber "needs you" thread
   leads from nav → tab → row → button. Amber = needs a person; green =
   healthy/live; gray = not started. Counts live in filter tabs, never in
   stat cards. Raw ids demote to mono text and expanders.

   Contents
     01 tokens              10 studies list (elevated + quiet rows)
     02 reset + base        11 study chrome (header, page tabs) + overview
     03 typography          12 documents
     04 focus + a11y        13 systems page + console
     05 controls            14 audit trail
     06 status + tone       15 states: loading / empty / failed
     07 auth screens        16 overlays: dialog, drawer, toast
     08 shell               17 domain surfaces (semantic, control, identity)
     09 home (three states) 18 responsive + motion
