Add an md-print element that paginates markdown into A4 landscape sheets holding two A5 pages, each with configurable columns. The preview modal exports through the browser print dialog.
Paragraphs, lists, and tables split at word, item, and row boundaries; headings are kept with following content.
Add the bare d-form (d20) to the dice notation table, and note that role fences accept backticks or tildes with hyphen-capable attribute keys. Regenerate both reference copies from known.ts and mirror the notes in the skill and markdown docs.
The journal now owns command history and tracking, so retire the md-commander widget. Its dice engine was extracted to src/components/dice in the previous commit.
Removes the custom element, tracker/command stores, completions, useCommander, Emmet parser, the doc entry, test fixtures, and the known-element catalog entry (reference docs regenerated).
BREAKING CHANGE: :md-commander is no longer a known element; content using it now fails tttk check with TTTK-D001.
Move the skill to .agents/skills/tttk-authoring and point gen:skill-reference at it. Activate it by symlinking ~/.agents/skills/tttk-authoring to the in-repo copy.
Extend the reference drift guard to cover the skill copy now that it is versioned, and document activation in docs/development.md.
