/* Automatic itinerary landing page (automatic-itinerary/). Builds on site.css and the app UI kit
   in landing.css. Every illustration's finished state is the default, so the page reads the
   same without JavaScript or with Reduce Motion; assets/js/automatic-itinerary.js only adds
   the movement. Sources (Gmail, ChatGPT, Claude, Muse…) each get a small, recognizable
   treatment, but always as inputs flowing into Tripami's own UI. */
