/*
 * Markset in a TipTap editor. Load it after markset.css.
 *
 * The editor draws each construct with the renderer's ms- classes, so
 * markset.css styles most of it unchanged. Four constructs have a different
 * shape while they are being edited, because the rendered page replaces their
 * content and the editor cannot: a grid and steps hold their list, metrics its
 * table, and tabs show every panel at once. These rules give those shapes the
 * look of the rendered page. Everything is scoped to .ProseMirror, the class
 * TipTap puts on the editable element, so a page that also renders Markset is
 * untouched.
