/* ProvenanceTrace — provenancetrace.com
   One signed incident notice, answered under different evidence regimes.

   Layout: a fixed navy sidebar holds everything you manipulate (guided
   scenarios, then the evidence regime); the main column holds only the answer.
   smoke.html asserts no horizontal scroll at 390px and that the units table
   renders, so re-run it after changing anything structural here. */
