Release notes:

Minor Changes

• 4d6de27: reorganize greyscale tokens and update color preferences

Patch Changes

• 2ff49b7: updated button styles for outline and secondary

• 59f7935: Fix Jest module resolution failures and reduce Shiki bundle size

Jest Fix:

• Add chunkFileNames config to prevent double-dash filenames (e.g., combobox--ec3iibR.js) that Jest cannot resolve
• Move chunks to dist/chunks/ subdirectory for cleaner structure

Bundle Size Reduction:

• Switch from full Shiki bundle to fine-grained imports via shiki/core
• Reduce from ~300 language/theme chunks to ~16 bundled languages
• Total JS files reduced from 358 to ~163 (54% reduction)

Supported Languages: javascript, typescript, jsx, tsx, json, jsonc, html, css, python, yaml, markdown, graphql, sql, bash, shell, diff

Breaking Change:

• BundledLanguage type is now deprecated, use SupportedLanguage instead
• Only the languages listed above are bundled; other Shiki languages are no longer available out of the box

• 9eaf584: Fix npm publish failure by removing cross-package dependency from prepublish hook
