`width:"container"` — the viewer auto-fits the whole chart (axes + legend) to its pane, so

layer at the last point), drop the now-redundant `legend` (`legend:null`) AND reserve room with
`x.scale.domainMax` past the last point, or the labels spill off the plot's right edge.
- **Keep node `label`/`sub` concise.** The layout sizes each card to its content and spaces nodes
to avoid overlap, so short, scannable text reads best (and the card stays compact). Pair the
`label` with `icon`/`sub`/`meta` for context — don't ship a bare word.
