/*
 * CarTraceAI visual system — Evidence Trace, revision 2.
 *
 * This layer turns the functional foundation into one recognisable product:
 * a CT trace monogram, a single geometric icon family, evidence rails and
 * vehicle-dossier surfaces. It uses no framework, runtime icon package,
 * remote font, stock illustration or decorative claim the product cannot make;
 * reviewed interface paths are vendored and rendered by the native PHP layer.
