Add the "Button" component from notboring to my project.
It is licensed for use in my projects — notboring.dev/license. Please:
1. Create the component at a sensible path for this
project, named Button, from the source below.
2. Install what it needs: npm i framer-motion
3. Add the CSS to the project's stylesheet.
4. THE PART THAT NEEDS YOUR JUDGMENT. The CSS reads
these custom properties and does not define them:
--font-ui
--ink
--ink-rgb
--on-ink
They are notboring's design tokens. Map each one to
whatever this project already uses for the same
job — its own ink, ground, surface and UI font —
rather than defining them as new globals. If the
project has no equivalent, define it locally on
the component's own root so nothing leaks out.
Anything ending -rgb wants three bare numbers,
because the CSS builds rgba() from it.
Keep the comments. They say why the numbers are what
they are, and they are most of what makes this worth
copying rather than rewriting.

Save, saving, saved. One pill, and it is the same pill
the whole way through.
THREE STATES, ONE OBJECT. The obvious build swaps the
button for a spinner and the spinner for a check, and
each swap is a cut — the thing you pressed goes away and
something else stands where it was. Here nothing goes
away. The pill stays the pill; only what is written on
it changes, and the pill's WIDTH follows the words on a
spring, so "Save changes" narrowing to "Saving" reads as
the object taking a breath rather than as a replacement.
The labels are stacked in one place and slide UP through
it in order — the leaving word rises out as the arriving
one rises in — so the sequence has a direction, the way a
counter does. A crossfade in place would say the button
was uncertain; a lift says it moved on.
THE WIDTH IS MEASURED IN LAYOUT PIXELS. Each label is
drawn once, hidden, and read with offsetWidth. Not a
The rest — the source and its comments — is what you are buying.
