A prompt box that grows as you write, listens when you ask it to, types a suggestion in for you, sends, streams, and can be stopped.

Add the "Composer" 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 Composer, 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-2
--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.

/* ══ Composer ═════════════════════════════════════════════
A prompt box, and the exchange it starts.
IT GROWS, SENDS, STREAMS, AND CAN BE STOPPED — and the four
are one object. The obvious build is a text field with a
button beside it and a chat log somewhere else; this puts
the box at the foot of the block, the thread above it, and
has the box GIVE ROOM to the thread as it shrinks back after
a send. The two are anchored to the same bottom edge, so
nothing above ever jumps to make space for what is below.
AT REST THE BOX IS IN THE MIDDLE OF THE BLOCK, with three
things you might ask hanging over it. Press one and it types
itself into the field, a letter at a time, because a
suggestion that simply appears in the box is a form filling
itself in and one that types is a hand being lent. The first
send moves the box down to the foot — one tween on its lift
— and the thread takes the room it gives up, so the box's
move IS the thread arriving. Press into the box and it grows
by a line: a field that is being written in is a field with
The rest — the source and its comments — is what the plan opens.
