/*
 * Xiao Ao Travel — semantic flight motion
 *
 * This layer deliberately styles only real booking information already
 * present in the planner.  In particular, the boarding ribbon and aircraft
 * mark are rendered by app.js only after a confirmed flight exists; this CSS
 * never manufactures an aircraft, airline, airport, seat, or ticket state.
 *
 * It is loaded after update.css.  Ground-transfer uses the same base booking
 * field, so every flight-specific selector explicitly excludes `.visual-ground`
 * or requires the existing `.boarding-ribbon` element.
