A primitive is one control you drop into a form or a toolbar — a segmented control, an input with an addon, a tag field.
Selection
5 of the 54 primitives in the catalog. Every one is a single file of plain markup and Tailwind classes — paste it and it works.
Segmented Control
Pick exactly one, built as a radio group rather than three buttons, so a screen reader says which is chosen — with a sliding indicator that animates one transform instead of repainting backgrounds.
Emoji Reactions
A reaction row where each pill is a toggle that says whether you are one of the count, plus a short picker — announced with names, since "👍 3" is read as a shrug by a screen reader.
Radio Card Group
Plans and shipping methods as cards, built on real radio inputs so the arrow keys, "2 of 3" and form submission are the browser's — with selection drawn as a tick, not only a colour.
