/**
 * The look, borrowed from `expense/` and `read/`: a rail, a column, hairlines,
 * and colour rationed to the things that mean something.
 *
 * The palette is Notion's, for the reason those apps use it — this is a page
 * somebody opens several times a day, and the fastest interface to learn is one
 * that behaves like an interface they already know.
 *
 * Two things are specific to this app:
 *
 *   the figure     any number that can be asked where it came from gets a
 *                  dotted underline. That convention is the whole of the
 *                  discoverability of the trace panel, so it has to be
 *                  consistent everywhere and quiet everywhere.
 *
 *   the tablet     this is used at a meeting table and on site. Columns shrink
 *                  and then stack; nothing hides behind a menu, because a menu
 *                  is a thing to explain while a client waits.
