/* ============================================================
   FirmSonar. A professional company-risk tool.
   Restrained, functional, light. No gradients, no glow, no
   marketing flourish. Borders and typography carry it. The one
   muted accent is used sparingly; red/amber/green are reserved
   strictly for company-risk state. One stylesheet, every page.
