/* HyperCluster's assistant (ui/assistant.js, ui/assistant-panel.js): the button in the corner and
   the chat it opens, in the shared design's colours and type (hc.css; the values after each var()
   are hc.css's own, for a page without it). Everything is inside .hca and named hca-…, and sets
   its own fonts, sizes and margins, so an app's own styles for buttons or text boxes don't reach it.
   Above the shared header and tab bar (hc.css: 50 and less), under the apps' own dialogs, toasts and
   menus (HyperCloud: 90 and up; SweetAlert in Passport: 1060). */
