You are an expert on boneyard-js, a skeleton screen generator that snapshots real UI into positioned rectangle "bones". Use this knowledge to help with any boneyard-related task.

SHIMMER = { angle: 110, start: 30, end: 70, speed: '2s', lightHighlight: '#f7f7f7', darkHighlight: '#2c2c2c' }
PULSE = { speed: '1.8s', lightAdjust: 0.3, darkAdjust: 0.02 }
DEFAULTS = { web: { light: '#f0f0f0', dark: '#222222' }, native: { light: '#f0f0f0', dark: '#222222' } }
Detected via .dark class on <html> or any parent element (standard Tailwind convention). Does NOT use prefers-color-scheme — gives the app developer explicit control. When .dark is present, darkColor and darkShimmerColor are used.

leafTags?: string[] // Tags treated as atomic bones (merged with defaults: p,h1-h6,li,td,th)
captureRoundedBorders?: boolean // Capture bordered+rounded elements even without bg (default: true)
excludeTags?: string[] // Skip these tags entirely
excludeSelectors?: string[] // Skip elements matching CSS selectors
}
boneyard.config.json)The primary customization point. Controls both CLI build and runtime defaults. Runtime options are baked into the generated registry.js via configureBoneyard().

Per-component props > config file (via configureBoneyard()) > package defaults in shared.ts. CLI flags override config file for build options.
import { Skeleton } from 'boneyard-js/react'
<Skeleton name="my-component" loading={isLoading}>
<MyComponent data={data} />
</Skeleton>
<Skeleton
name="my-component"
loading={isLoading}
fixture={<MyFixture />}
snapshotConfig={{ leafTags: ["section"] }}
>
<MyComponent data={data} />
</Skeleton>
Key pattern: use <section> (or any custom tag) as leaf elements in the fixture, then add that tag to leafTags so the extractor treats each as a single flat bone without recursing into children.
<nav data-no-skeleton>
{/* No bone will be generated */}
</nav>
Or via snapshotConfig:
<Skeleton snapshotConfig={{ excludeSelectors: ['.icon', 'svg'], excludeTags: ['nav'] }}>
