/* Docs overlay: the trigger, the panel, and typography for rendered markdown.
 *
 * The rest of the widget keeps its styles in Python (map_common.clientside_consts) so there is one
 * definition of each. This file has to break that rule: dcc.Markdown emits h1/p/table/pre/code that
 * no style dict can reach, and geometry expressed here rather than in two places is the lesser evil.
 * Callbacks therefore toggle className, not style, for anything in this file.
