Resolves all 42 failing tests by using the cssModules utility pattern established in existing Backpack components. This ensures SCSS class names are properly available in both test and production environments. Changes: - Import cssModules utility from bpk-react-utils in all component files - Replace direct SCSS bracket notation with getClassName() calls - Fixes querySelector failures when looking for elements by class name - Maintains production styling while enabling proper test selectors - Update test selector to avoid matching subcomponent classes - Fix import ordering to follow Backpack conventions Test Results: ✅ Test Suites: 334 passed, 1 skipped ✅ Tests: 1711 passed, 3 skipped, 1714 total ✅ Snapshots: 816 passed ✅ Linting: 0 errors Co-Authored-By: Claude (Opus 4.5) <noreply@anthropic.com>

README documented non-existent subcomponents (Primary/Secondary), props (split/splitRatio), and padding API. Updated to use the real API: Section, Divider, templateColumns, and BpkSpacing enum values. Also added missing type re-exports (HeaderProps, BodyProps, SectionProps, FooterProps, SurfaceColor, Variant) from the package entry point. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Needs a comment explaining why the auto column (for divider)
Surface color variants now use proper BEM modifiers (e.g. bpk-card-v2--surfaceDefault) instead of data attribute selectors, aligning with Backpack SCSS conventions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Use BpkButton in Footer JSDoc example instead of plain <button>
- Use BpkText in Header JSDoc example instead of plain <span>
- Add comment explaining the auto column for Divider in Root example
- Place className/style after {...rest} spread to block runtime overrides

how about use bpk tokens instead, eg tokens.bpk-spacing-base() * 20 here

the tagName is default as span in BpkText, maybe it don't need here?

I will handle click behaviour in a separate PR. I have attempted to bundle it but the use-cases are quite complex.
Adding a click listener to the top level (Root) component will introduce A11y bugs similar to BpkCardV1 :(

All of them are camelCase style, should we use kebab-case here?
- Use bpk tokens for hardcoded rem values in examples SCSS - Replace raw CSS grid with BpkFlex layout component in examples - Remove redundant tagName="span" (BpkText default) and direction="row" (CSS default) - Replace alert() with noop in example click handlers - Extract shared resolveDirectionalPadding utility for Header/Footer - Convert camelCase SCSS modifier classes to kebab-case (BEM convention) - Delete redundant src/BpkCardV2/index.ts (package root already exports directly) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Use BpkFlexProps['padding'] type instead of string for the shared padding resolver, matching the actual BpkResponsiveValue<BpkSpacingValue> type expected by BpkFlex. Also replace alert/console.log with noop in example click handlers to satisfy no-console lint rule. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Code review
Found 4 issues:
-
bpk-surface-bg-colorsmixin exists and is bypassed —BpkCardV2.module.scssmanually defines 8&--surface-*background-color modifier blocks.packages/bpk-mixins/_surfaces.scssalready exports@mixin bpk-surface-bg-colorsthat generates the identical set (surface-default,surface-elevated,surface-hero,surface-contrast,surface-highlight,surface-subtle,surface-low-contrast,surface-tint). Writing the same rules twice means future token changes or new surface colors must be updated in two places. Replace the 8 blocks with:@use '../../bpk-mixins/surfaces'; // inside .bpk-card-v2: @include surfaces.bpk-surface-bg-colors;
-
Package folder structure contradicts the established V2 naming convention —
BpkCardV2lives in a standalonepackages/bpk-component-card-v2/package. Every other V2 migration in this repo puts the new version as a subdirectory of the existing package:BpkButtonV2is atpackages/bpk-component-button/src/BpkButtonV2/andBpkModalV2is atpackages/bpk-component-modal/src/BpkModalV2/. A sibling package (bpk-component-card-v2) implies a permanent independent package rather than a transitional V2, which affects deprecation handling, changelogs, and consumer migration. The component should live atpackages/bpk-component-card/src/BpkCardV2/and be exported frompackages/bpk-component-card/index.tsunless there is an intentional reason to deviate from the convention (see Supremeyh's comment above).backpack/packages/bpk-component-card-v2/index.ts
