A two-state button: the slash writes itself across the eye, and the password comes up under it left to right.

Add the "Toggle" 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 Toggle, from the source below.
2. It needs nothing beyond 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-code
--font-ui
--ink
--ink-2
--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.
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.

/* ══ Toggle ═══════════════════════════════════════════════
A button with two states, drawn as the one every product
has: the eye over a password.
THE SLASH IS DRAWN, NOT SWAPPED. Every icon set ships an
eye and an eye-with-a-line-through-it as two separate
glyphs, and every product crossfades between them — which
is two eyes dissolving into each other for 150ms, the one
moment the control looks broken. There is one eye here, and
the line is a stroke that writes itself across it from the
near corner and erases back to the same corner. A stroke
that is drawn tells you which direction the state went; a
glyph that fades tells you nothing.
AND THE CHARACTERS COME UP UNDER IT, LEFT TO RIGHT, the way
a curtain opens — 30ms apart, so the word arrives as a word
rather than as nine dots all changing their minds at once.
Hiding runs the other way, from the end back to the start,
because that is the same curtain closing.
ONE NUMBER: how far open it is. The slash's length, the
pupil, and every letter's turn are read off it.
The rest — the source and its comments — is what the plan opens.
