01 · Colour

The slate ramp

Fifteen steps, and every semantic token in the light, paper-like and deep-blue modes resolves to one of them. The five anchors of the original palette are still here: 950, 850, 700, 500 and 50.

02 · Data colour

Eight slots,
fixed order

The interface palette cannot carry series identity. The brand slate has an OKLCH chroma of 0.055, below the 0.10 floor where a hue stops doing identity work: used as a series it reads as grey. The data family is derived, with the same blue saturated into slot one.

Order is the safety mechanism, so slots are assigned in sequence and never cycled. A ninth group folds into Other, becomes facets, or gains a second encoding.

05 · Glass

Four textures,
one material

Glass is the material of every control in this system. It has five layers and all of them matter: a vertical gradient fill, a backdrop blur, saturation, a specular highlight on the top edge and refraction on the bottom. Remove any one and the result reads as a plain translucent panel.

The four textures differ in how much of the background survives. Thin lets almost everything through, deep almost nothing. Frost is the only one that carries grain: a desaturated turbulence over the fill, which is what separates frosted from merely translucent.

.glass-frost30pxAnything that carries text of its own: toolbar, command palette, sheet, modal
.glass-deep56pxFull-width chrome that must separate itself from the page: navigation bar, docked footer
.glass-accentinheritsThe one selected or primary control in a group, never more than one at a time
Liquid layer

The fifth material is not a fifth texture

Glass filters itself, so the text it carries goes through the blur with it. That is why glass never merges: fusing two neighbouring controls would melt both labels.

Liquid splits the material from the content into two layers stacked in one grid cell. The silhouette sheet, behind, is the only filtered thing on the page and carries the goo filter and the shadow. The real DOM rides on top, unfiltered, crisp, with its focus ring, hit area and ARIA intact.

The two layers are mirrors: same display, same gap, same box per unit. That is how the drop sits exactly under the control without a line of JavaScript measuring anything, and it is also the price. A cluster unit has a fixed size, because a width that depends on the text can only be mirrored by measuring the text.

FilterDeviationSlopeInterceptBridges up to
#pure-goo-tight420-7.834px
#pure-goo618-76px
#pure-goo-wide1216-6.1710px
Liquid layer

Five reads, and none of them writes a transform

Every liquid animation writes the registered tokens and the composition stays the one transform declaration in the chapter. That is what lets the material move without reopening the defect of two rules fighting over the same element.

The tokens are registered with @property, which is what makes them interpolate. An unregistered custom property is text: it jumps from one frame to the next, so a keyframe writing --liquid-swell would step instead of flow.

What the library does with a spring, this does with a curve, and the difference is declared rather than hidden. A spring overshoots on its own and keeps going past the target; reproducing it means integrating every frame, which is JavaScript. What crosses over is the shape of the motion, and the shape is what you recognise: the bridge stretching, the neck thinning, the drop letting go.

Light layer

Glass stands still. The light does not.

The glass in this language is a still material: it blurs what is behind it, lights the top edge and pools a shadow at the base, and it does all three the same way wherever the pointer happens to be. That is what an honest material does, and it is why glass never needed a script.

The light layer does not change the material. It adds the source. A real glass surface has a highlight that travels when the light travels, a rim that lights on the side the light comes from, and a depth that only shows when the observer moves. The pointer is the observer, and it is the one thing on this page a stylesheet cannot read. That, and only that, is why this layer ships with JavaScript.

The contract is three numbers. light.js measures a box and writes --light-x, --light-y and --light-near. It knows nothing about highlights, rims, tilt or magnets: no effect name appears anywhere in that file. Every appearance decision lives in light.css, which is why a new effect in this layer touches no JavaScript at all.

Tilt

The surface turns toward the pointer and settles back on its own. No second state, no hover rule.

Three shapes, one job. The elapsed reading is mono with tabular figures: a proportional face would make the whole line twitch every tenth of a second. The sweep across the label is a pseudo-element moved by transform, not by background-position, so it composites off the main thread.

Opening does not animate height. The body leaves the flow with [hidden] and each step settles with a staggered fade on the way back. Animating grid-template-rows would buy a continuous transition at the cost of layout on every frame, and the language does not pay it.

Each chunk enters on opacity plus a 2px nudge, staggered by --stream-step. The original blurred every chunk on entry; filter: blur repaints the box each frame and never composites, so the entrance was rewritten. It reads the same, it does not cost the same.

Twenty-one recipes, remapped onto the scale that already existed

The recipes come from the transitions.dev catalogue by Jakub Antalik, and they were not copied: they were remapped. The catalogue carries its own scale, seven durations and six curves, and this language has six durations and five curves and forbids a new one.

The remap follows the rule the catalogue itself states, match by use and not by number. A 300ms modal close becomes --duration-2 at 150ms because both are "modal close", even though the numbers are far apart. The dominant catalogue curve, cubic-bezier(0.22, 1, 0.36, 1), is --ease-out-expo here to three decimal places of intent.

Three px values were born with the layer, and they are blur radii, not a scale: --motion-blur-1, -2 and -3. They blur the element itself while it moves and clear on settle, which is the opposite of glass, where the blur is on the backdrop and stands still. Mixing the two families is how a card ends up blurred at rest.

Rules the build
has to pass

Everything before this section is material: colour, type, space, glass, motion. This one is behaviour. It is the part no screenshot shows and every user meets in the first ten seconds: whether the keyboard reaches the control, whether the tap lands, whether the form hands the error back before the round trip or after it.

Three levels. Must fails the build or the review. Should is the default, and leaving it needs a written reason. Never has no exception.

Live: focus and target

Press Tab. The ring appears from the keyboard and stays hidden from the pointer, and it turns to ink over glass. The small round control is 16px of drawing and 24px of target: switch the outline on and its hit area shows up well outside the shape, while the pills already clear the floor on their own. It carries no label, so it carries an accessible name instead.

What the demo proves

Send it empty. Nothing was disabled, the browser did not take over, the two errors land under their own fields and the caret goes to the first one. Fix them and send again: the button keeps its label and grows a ring, and the result is announced to a screen reader through a polite live region rather than only drawn.

The textarea takes Cmd or Ctrl with Enter. The email field has its own keyboard on a phone, its own autofill entry, and spellcheck off. Every value is trimmed before it is read, which is what stops a pasted address with a trailing space from failing validation for a reason nobody can see.

How many flavours should we launch?

Launch size

The question the agent asks before it acts. Options are real radios inside a fieldset: one choice, an accessible name each, arrow-key navigation, and a legend that a screen reader can announce even though the design shows no label.

Agent · Prompt bar

The field is --text-field, 16px, not --text-12: below that iOS zooms the page on focus. The bar never blocks typing or paste. @ opens sources, / opens commands, and the key you type is mono while its description is language.

Agent · Command search
  • Forecast summer demand
  • Find waffle cone suppliers
  • Compare seasonal flavours
  • Draft flavour launch plan
  • Check cold-chain status

Type to filter. Empty, sparse, dense and error are four designs, not one, and the empty state always offers the next step: a page with no way out is a defect. The list keeps overscroll-behavior: contain so the finger stops at its edge instead of scrolling the page behind.

Agent · Inspector
Flavour card
Layout
Shape

Every field here is a number, so every field is mono with tabular figures; a proportional face moves the caret between columns as the digits change. The unit lives inside the field, not beside it, so the target stays one thing.

Agent · Selection actions

Pistachio holds the top slot all weekend. Churn it first thing Saturday so the batch has time to firm up before the afternoon rush.

The mark is --accent mixed down to a tint, so it stays legible in all four modes without a colour of its own. The bar arrives with fade-scale: it settles into place and never jumps.

Code is typography, not data, so the highlight uses ink levels rather than
        hues. Identifiers and literals sit at --text, reserved words and
        calls at --muted in medium weight, comments and line numbers at
        --secondary. None of the eight chart slots appear here: those
        carry series identity, and a keyword is not a series.

One table base carries all three: the filtered list, the record grid and
        the proposed edit. The row that leaves and the row that enters take state ink, tinted by
        color-mix against transparent, so no new colour enters the
        language to describe a diff. Dates and counts use .num because
        they get compared down the column.

      

    



    

      Icons
      
Sixty-five, drawn to the same geometry as everything else

    


    

      

        
Until 1.6.0 the language had no icons, and the absence showed on every screen built
        with it: each project brought a set in from outside, with a different box, a different
        weight and a different cap, so the one drawing on the page that did not belong to the
        page was the one that repeated most often.

        
The weight is the whole point, and it does not live in the sprite file. It lives in
        .icon as var(--stroke), the same
        token as the spinner ring and the checkbox mark.
        non-scaling-stroke keeps it equal across all three sizes:
        without it the stroke shrinks with the box and a 16px icon reads lighter than a 24px one
        in the same bar.

        
Three sizes and no more: 20 for a control, 16 for metadata, 24 for a heading. The
