Eight tools and one halo, which is the only thing that moves.

Add the "Toolbar" 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 Toolbar, from the source below.
2. Install what it needs: npm i lucide-react
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:
--card
--font-ui
--ink
--ink-3
--ink-rgb
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.

/* ══ Toolbar ══════════════════════════════════════════════
Seven tools in a pill, and one halo.
EIGHT HOVER STATES IS SEVEN TOO MANY. The obvious build
gives every tool a background that fades in under the
pointer, and moving along the bar is then seven things
appearing and seven things disappearing, each on its own
clock and each a hair out of step with the one before.
This bar has ONE halo. It slides to whichever tool the
pointer is over, on a spring, so a pointer crossing the
bar reads as a single object following a finger rather
than as a row of lights.
The rest — the source and its comments — is what you are buying.
