For developers
The install command lives in the “Component source” block below — a signed link that stays valid for 24 hours.
Technical notes
The component is self-contained: one file, no dependencies, its own palette in the local --vibeui-button-014-* variables. Server component: no hooks. The label is always in the markup, but its max-width is zero and grows to 12rem on hover and focus-visible — that way the button expands in the flow instead of covering its neighbours. The action name is duplicated in aria-label. The plus is drawn with two bars.
