A list you drag into order: the row leans with its speed, the others make room, the ranks roll.
The prompt16,690 characters
Add the "Reorder" 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 Reorder, from the source below.
2. Install what it needs: npm i framer-motion 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-4
--ink-5
--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.

/* ══ Reorder ══════════════════════════════════════════════
A list you drag into order. The row you hold follows the
finger; the others make room; the numbers roll.
NOTHING IS MEASURED. Framer's Reorder would animate this by
reading screen rectangles, and every block on this wall is
drawn at a fraction of its own size — see zoomOf. Here a
row's place is a slot number times a row height, and that
is where its spring goes; the row being held is the
finger's delta through the zoom, and the slot it is over
is that same number divided by the same height. Arithmetic
on both sides, so the list behaves the same at any scale
and nothing watches the DOM.
THE ROW LEANS WITH ITS SPEED. Read off the velocity of its
own position, the way the switch's knob reads its stretch:
a row pulled quickly tips into the pull, and one set down
The rest — the source and its comments — is what the plan opens.
