/* Family Tree on the web (server/web/pages/tree.js and its tree-*.js siblings;
   the phone's is components/pages/TreePage.tsx and components/tree/*).
   Every colour is a theme variable, so all the themes, light and dark, come
   for free; the photo viewer alone is black whatever the theme, as Photos' is.

   The tree is the page: on the Tree tab it fills everything under the tabs
   and nothing scrolls — the canvas pans. Everywhere else is one column that
   scrolls, read at 320px as often as at 1440. Every control is at least 40px
   tall, and nothing is said in colour alone. */
