/* The vineyard blocks: their toggle, their legend and their pins. See js/blocks.js
   (the overlay on the relief) and js/ui.js (the toggle and the legend).

   Internal data, so all of it shows only with all names on: the toggle as soon
   as blocks.json has loaded, the legend and the pins while the toggle is on
   (html[data-blocks="on"]). Where each goes:
   - a wide window: the toggle at the left of the names switch, the legend at
     the right under the names, where ui.js takes its room off the model's;
   - an upright phone: the toggle at the right of the tour's button, the legend
     between them and the list of places, which gives up the room it takes;
   - a small phone on its side: the toggle beside the switch, the legend at the
     foot of the column at the left, the list giving up the room again. */
