Scorecard Row

A single dimension row in a scorecard: name + GradeBadge + numeric score + optional details. Used by ScorecardTemplate to render each scored category (Performance, Coverage, Adoption, ...).

Rendered from the story the storybook (a11y) CI gate runs axe against — the preview can't show something that hasn't been verified.

Install

Two equivalent paths — the URL works in any shadcn-CLI setup; the alias works once you've registered @interlace in your components.json.

Via shadcn URL
npx shadcn@latest add https://ds.interlace.tools/r/scorecard-row.json
With the @interlace alias
npx shadcn@latest add @interlace/scorecard-row

Behavior

What this component does — the keyboard path, the measured colour, the text equivalent and the states it can be in. Every figure below is read out of the test or the source that enforces it by scripts/build-behavior-map.mjs, so nothing here can outlive the gate that keeps it true.

Every semantic colour pair this component's own source uses, measured against the shipped hexes in all 4 theme × scheme combinations. The tightest is card-foreground on card at 14.69:1 (harbor · dark), against a floor of 4.5:1.

card-foreground on cardcopy in a card19.65:115.71:118.72:114.69:14.5:1SC 1.4.3

Text pairs are held to 4.5:1 (WCAG 2.2 SC 1.4.3); borders, rings and chart axes to 3:1 (SC 1.4.11 non-text). Bold is the worst cell in the row — the one a brand fork has to keep an eye on.

Where it renders, how narrow it survives, and whether its lines are inside the coverage gate — three answers a consumer needs before the paste, not after the bug.

Render boundary
server component

Renders during SSR / RSC with no hydration cost. It can be imported from a server component without pulling the page into the client.

Minimum viewport
MIN_VIEWPORT = 320

Declared, not assumed. Below 320 CSS px the preflight contract draws a dev-mode outline — how to switch it on.

Coverage gate
not in the gate

The 100% gate currently covers src/charts/**/*.{ts,tsx} and src/lib/**/*.{ts,tsx} and src/primitives/{button-variants,data-state-model,meter-scale,skeleton-variants}.ts and src/primitives/{alert,aspect-ratio,avatar,badge,box,breadcrumb,button,callout,card,checkbox,container,data-state,focus-ring,grade-badge,grid,input,label,meter,pagination,published-date,reading-time,section,section-boundary,separator,skip-link,stack,stat-strip,tag,textarea,typography,visually-hidden}.tsx. This file is outside it — the glob widens in phase 7.2.

History

This component is at v1.0.0, first shipped in @interlace/ui 1.0.0. The version is stamped as a banner into the file the install writes, so the copy in your tree says which one you have — compare it with the number above before deciding whether to re-run the install.

No release note names this component yet. It shipped with the release above and has not changed since — see the full changelog for what moved elsewhere in the DS.

Import

Public API
import { MIN_VIEWPORT, ScorecardRow } from '@/components/ui/patterns/scorecard-row';

Anatomy

Extracted from the primitive's JSDoc header. The source is the only documentation that can't drift.

<article data-slot="scorecard-row" data-min-viewport="320">
    <header><h3>{name}</h3> <GradeBadge /> <span>{score}</span></header>
    {details && <div>{details}</div>}
  </article>

API reference

Parsed from the type declarations in the source — the same file the install writes into your tree, so this table can't drift from the component you get.

ScorecardRowProps

Also accepts every <article> attribute.

PropTypeDescription
name*React.ReactNodeDimension name (e.g. "Performance", "Coverage").
grade*GradeValueWCAG-style letter grade.
score*numberNumeric score (0-100). Rendered tabular for column alignment.
captionReact.ReactNodeOptional sub-line (e.g. "12 of 14 rules passing").
detailsReact.ReactNodeOptional detail content under the header (chart, table, callouts).
loadingboolean

Skeleton

Pass loading and the component renders a shape-matched <Skeleton /> in its own place — same box, so nothing reflows when the data lands. Below is the same story with loading={true}.

Usage
<MIN_VIEWPORT loading={isPending} />

Accessibility

Every story for this component is rendered headlessly and checked with axe-core (wcag2aa, wcag22aa, best-practice, ACT) on every PR. That gate has no continue-on-error, so what ships has zero known violations.

What follows is what static analysis can see. Axe cannot press a key and never sees an overlay open, so the operable-without-a-mouse claim lives in Behavior instead, where the keyboard path is replayed step by step.

Focus + keyboard behaviour
Native element semantics — no interaction layer to get wrong.
Focus ring (WCAG 2.2 SC 2.4.13)
Not focusable — no focus indicator required.
Reduced motion
No animation to gate.
ARIA in the source
None — semantics come from the element or the Base UI primitive rather than hand-written ARIA.

Examples

Minimum viewport

This primitive declares MIN_VIEWPORT = 320 CSS px (DESIGN_PRINCIPLES #14). When mounted in a container narrower than this, the preflight contract draws a dev-mode outline so the regression is visible during local development.

Opt-in to the dev-mode warning
<body data-interlace-dev>...</body>

Add the data-interlace-dev attribute to the body in development builds only — preflight then outlines any primitive whose container is below its declared data-min-viewport.
