Design System
src/app.css defines one dark skin for the application and demos. The excerpts below preserve the values in the repository snapshot; they are not a redesigned approximation.

--animate-accordion-down: accordion-down 200ms cubic-bezier(0.4, 0, 0.2, 1);
--animate-accordion-up: accordion-up 200ms cubic-bezier(0.4, 0, 0.2, 1);
--animate-pop-in: pop-in 140ms cubic-bezier(0.16, 1, 0.3, 1);

--animate-fade-out: fade-out 100ms ease-in;
}ink-950 is the base canvas and ink-50 is the primary foreground. Brand tokens form the teal interaction accent; accent-500 is the separate magenta accent. The CSS values above, rather than those descriptions, are authoritative.
Motion definitions
@keyframes accordion-down {
from {
height: 0;
}
to {
height: var(--bits-accordion-content-height);
}
}
@keyframes accordion-up {
from {
height: var(--bits-accordion-content-height);
}
to {
height: 0;
}
}
@keyframes pop-in {
from {
opacity: 0;
transform: scale(0.96) translateY(-2px);
}
to {
opacity: 1;
transform: none;
}
}
@keyframes fade-in {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
@keyframes fade-out {
from {
opacity: 1;
}
to {
opacity: 0;
}
}Accordion height comes from Bits UI’s --bits-accordion-content-height custom property. Overlay content uses the shared panel surface and animate-pop-in where it enters visually.
Base behavior
@layer base {
html {
color-scheme: dark;
}
body {
background-color: var(--color-ink-950);
color: var(--color-ink-50);
font-family: var(--font-sans);
-webkit-font-smoothing: antialiased;
}
::selection {
background: color-mix(in oklch, var(--color-brand-500) 40%, transparent);
}
:focus-visible {
outline: 2px solid var(--color-brand-500);
outline-offset: 2px;
}
}The global focus-visible ring is part of the base accessibility skin. Component demos may add state styling, but should not remove this fallback.
Shared skin utilities
Buttons
@utility btn {
display: inline-flex;
align-items: center;
justify-content: center;
gap: 0.5rem;
border-radius: 0.625rem;
border: 1px solid var(--color-ink-800);
background-color: var(--color-ink-850);
padding: 0.5rem 0.9rem;
font-size: 0.875rem;
font-weight: 500;
color: var(--color-ink-50);
transition: background-color 120ms ease, border-color 120ms ease, opacity 120ms ease;
cursor: pointer;
user-select: none;
&:hover {
background-color: var(--color-ink-800);
}
&:disabled,
&[data-disabled] {
opacity: 0.45;
cursor: not-allowed;
}
}
@utility btn-primary {
border-color: transparent;
background-color: var(--color-brand-500);
color: var(--color-ink-950);
font-weight: 600;
&:hover {
background-color: var(--color-brand-400);
}
}
@utility btn-ghost {
border-color: transparent;
background-color: transparent;
&:hover {
background-color: var(--color-ink-850);
}
}
@utility btn-sm {
padding: 0.3rem 0.6rem;
font-size: 0.8125rem;
}Use btn as the base and add btn-primary, btn-ghost, or btn-sm as modifiers.
Containers
@utility card {
border-radius: var(--radius-card);
border: 1px solid var(--color-ink-800);
background-color: var(--color-ink-900);
}
@utility panel {
border-radius: 0.75rem;
border: 1px solid var(--color-ink-800);
background-color: var(--color-ink-900);
box-shadow: 0 18px 40px -18px rgb(0 0 0 / 0.8);
}card is the durable in-flow surface. panel adds the shadow used by floating menus, popovers, and dialogs.
Inputs and compact metadata
@utility input {
width: 100%;
border-radius: 0.625rem;
border: 1px solid var(--color-ink-800);
background-color: var(--color-ink-950);
padding: 0.5rem 0.75rem;
font-size: 0.875rem;
color: var(--color-ink-50);
&::placeholder {
color: var(--color-ink-600);
}
&:focus {
border-color: var(--color-brand-600);
outline: none;
}
}
@utility chip {
display: inline-flex;
align-items: center;
gap: 0.35rem;
border-radius: 999px;
border: 1px solid var(--color-ink-800);
background-color: var(--color-ink-850);
padding: 0.1rem 0.55rem;
font-size: 0.75rem;
color: var(--color-ink-200);
}
@utility muted {
color: var(--color-ink-400);
}input owns the baseline text-field surface and focus border. chip is the compact pill used for category or status metadata. muted changes only foreground color and is safe to combine with layout and type utilities.
