  The base rules of ProseMirror, copied from prosemirror-view/style/prosemirror.css (MIT, Copyright (C) 2015-2017 Marijn Haverbeke and others).
  TipTap would inject them into a <style> element; injectCSS is off so that a strict style-src stays possible, and the page serves them
  here. editor/test/bundle.test.js compares this block with the package, rule by rule, so an upgrade that changes them fails a test.

  The editor's stylesheet (NT-030), served by the instance next to notetaking.css. The editor's script builds the

  design tokens of notetaking.css only. TipTap does not inject a <style> element of its own (injectCSS is off), so a
