/* ============================================================================
   Traceability demo: module-specific components.

   Linked THIRD, after design-tokens.css + app-shell.css. Everything builds on
   the tokens; the shared chrome (title row, tabs, toolbar, table, buttons,
   inputs) comes from app-shell.css and is consumed as-is, never restyled.
   Trimmed from gold-coast's app.css to the trace view + its detail panels.
