<!--
  dock sample app: hotel guest page. One page per hotel, sent to guests before they arrive: the entrance on a map,
  the page in mn, en, ja, ko, zh or ru (#lang=, else the browser's language), the hotel's own instructions, a card
  to show a taxi driver, a walking route from where the guest is, and the door's QR to print. No gate photo: the API
  serves it only to a names:write key, and a guest page's key is in every guest's browser.
  The hotel is a building code or a door link from a QR (#door=7QSVX), the door name it holds (#name=Сансар зочид
  буудал), or, until it has either, a place name to search (#place=Kempinski). Hotels write instructions in mn and
  en only: other languages show the English text and say so. Never a machine translation passed off as theirs.
  Serve sdk/js over http (npm run build, then e.g. `npx serve .`) and open /examples/hotel.html#key=dk_...&place=...
  The key needs door:read, geocode:read, route:read and tiles:read; a free key has them. #name also needs the
  door_names feature on the key's org, else 403 feature_off shows under the map.
