/* Daily Life Doc, round 13 (zone XF): the expert's layout, drawn as the page "Expert Plans" draws "The expert's
   screens" (docs/artifact/expert/index.html, the css of .win, .wnav, .ni, .whead, .emp, .cpb, .ephone).
   At a computer: the left list (#nav: Clients · To review · Calls, a rule, Knowledge base · Settings, with counts),
   then the head row (#top) and the open place (#page); pages opened over a place slide in over the head and the
   place (#stack). At 880 px and narrower: one column: the head row with the round More button, the row Clients ·
   To review · Calls under it, then the place; a client's page hides the row and shows its own back arrow.
   The client page's parts (.cp*) are in css/shell-client.css. js/shell/shell.js draws all of this. */
