Full mode became the default with all available content toolbar groups visible from the first render. The ribbon expand-and-collapse step was removed so readers could find tools directly.
Mini mode is selected with toolbarSize: "mini". In this release, toolbar buttons used a compact 32px profile and smaller spacing while keeping the same tools, generated HTML, form mirroring, and mount API.
The mode changes interface density rather than choosing HTML or Markdown output. The release was published at versions/0.0.3/editor.js; the current example uses the newer version described in the latest article.
