/*
 * Execution Timeline tab (Transaction Flight Recorder)
 * Design tokens come from design-tokens.css + app.css :root variables.
 *
 * The Execution Timeline surfaces the structured pipeline trace recorded by
 * IPipelineTraceRecorder (G23, 2026-05-12). Layout matches the rest of TFR
 * (card-on-card with subtle borders + Inter typography) so the new tab feels
 * native alongside Routing Decision / Event Timeline / Processor Comms.
