A rule with three rows folded inside it: press the count and its two halves run out to the edges.
The prompt10,600 characters
Add the "Separator" 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 Separator, 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-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.

/* ══ Separator ════════════════════════════════════════════
A rule with something between its halves.
A DIVIDER THAT ONLY DIVIDES IS A LINE, AND A LINE IS NOT A
COMPONENT. The one job worth giving it is the one every
long thread already gives it: hold the part nobody needs to
read, say how much of it there is, and open when asked. The
rule is not decoration between two rows — it is the lid on
what is missing between them.
THE HALVES PART, THEY DO NOT FADE. Opening sends the two
ends of the rule out to the edges of the card while the
hidden rows unroll in the space they leave; closing brings
them back together over the rows as they roll up. One
number does both, so the line always meets the rows it is
making room for at exactly their own height.
AND THE WORD STAYS PUT. The count sits at the middle the
whole time and turns its chevron over — a label that moved
with the halves would be a third thing traveling on a
control whose subject is two. */
The rest — the source and its comments — is what the plan opens.
