Three figures that roll to the period you pick, and lines that bend to match.

Add the "Stats" 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 Stats, 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:
--card
--font-ui
--ink
--ink-2
--ink-3
--ink-4
--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.
5. IF YOU CHANGE IT, GO ALL THE WAY. This block is
built for every state its object can really be
in — empty, one, full, refused, undone, pressed
twice, interrupted halfway — and not only the one
the demo opens on. Adapt it and the same standard
holds: work out that list before you write, and
build the whole of it. Never settle for the
minimum that makes the screenshot right. A
component somebody has to come back and finish is
the thing this was written to replace.
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.

/* ══ Stats ════════════════════════════════════════════════
Three figures for a period, and the period you can change.
THE FIGURES ROLL, AND THE LINES BEND. Switch from seven
days to thirty and each digit rolls to its new value, up if
the number rose and down if it fell — a counter turning,
not a label swapped — while the small line under it bends
from one shape to the other on one tween: every point is
mixed between the two sets by the same number, so the
three lines move as one weather changing.
AND THE LINE IS A MONOTONE SPLINE, the Chart's own. Seven
readings joined by straight segments is a zigzag, and at
this size a zigzag is noise; a plain cubic through the same
points invents lows that the data never had. Fritsch–
Carlson sets the tangent to zero wherever the series turns
and clamps any tangent pair whose squared sum passes nine,
so the curve is smooth everywhere and never leaves the box
its own points draw. A chart that invents a low is not a
style, it is a lie — and that is as true of a sparkline
thirty pixels tall as of the one it was written for.
The rest — the source and its comments — is what the plan opens.
