npm run storybookWhen to use it
In Dense data: Selects rows and filter values.
- Use it when: Agreeing, picking many, optional extras; the choice waits for the form.
- Not when: Exactly one of a short set (radio group), or a setting that applies at once (switch).
Instead:
- Radio group: One choice only.
- Switch: Applies at once.
- Select: Many options in a compact list.
Words
- Lead with the object, then the state: "Alert 2041 contained."
- Use numbers, not words for numbers.
- One verb per button. No "please", no exclamation marks.
- Use: Investigate, Filter, Assign, Escalated, Resolved. Avoid: Oops, Awesome, Please, Simply.
The labels components use, from the voice tokens:
content.action.commit: Savecontent.action.cancel: Cancelcontent.action.destroy: Deletecontent.action.retry: Retrycontent.action.empty-action: Change filters
See Voice and tone for the whole voice.

The component reads only component keys and semantic tokens, so it follows the brand and mode on <html>.
Tokens it reads
Checkbox reads 11 tokens of its own, each an alias of a semantic token. Each row is one part: its own token, the semantic it aliases, and the value it ends at. Change a semantic and every component that reads it follows; override one of Checkbox's tokens to change Checkbox alone.
Dense data decides what changes when you switch theme. Here a switch changes colors only, so the marked rows differ between light and dark; everything else holds steady.
