## Overview

This is a PHP travel-planning application centered on generating, reviewing, costing and saving itineraries, with AI assistance, hotel and route recommendations, cultural-place discovery, traveller accounts and administrative tools. The source index provides import/reference evidence for several connections, while excerpts confirm route, cost and hotel service behavior. The README is empty, and many listed endpoints and domain services were not sampled, so their internal relationships are shown only where the index supports them.
