Eliminates the 'classic' theme from theme lists, configuration, and code logic. Removes classic theme token files and CSS, updates documentation, and refactors theme hooks and context to only support 'light', 'dark', and 'system' themes. Cleans up unused auto theme logic and ensures all theme switching and CSS variable generation use the new approach.

Replaces 'systemModeOverrides' with a top-level 'dark' property in theme config for dark mode overrides. Updates ClickUIProvider and ServerClickUIProvider to merge dark overrides and generate CSS variables using light-dark() only for color variables, with separate handling for non-color variables. Cleans up config loading, adds getThemeValue utility, and updates Vite plugin to match new config structure.

Updated dayjs plugin imports to use explicit .js extensions in DateDetails.tsx. Refactored linkStyles.ts to use double quotes for consistency and converted linkClasses to an arrow function. Added import for global theme styles in index.ts to ensure styles are included when using the library.

Add Node.js environment to ESLint config, update .gitignore to exclude generated SCSS and CSS declaration files, and adjust VSCode settings to hide these files from search and file explorer. Refactor Vite config to bundle all CSS into one file, enforce consistent CSS module class names, and improve external dependency handling for React and other libraries.

Major documentation overhaul for Click UI theme configuration: rewrote BUILD_TIME_CONFIG_CLICK_UI.md as a full API reference, added CONFIG_ARCHITECTURE.md to explain config/plugin design, and updated README.md and config/README.md for clearer quick start and plugin setup. Added CLI bin/click-ui.js and bin/commands/init.js for config file scaffolding. Removed legacy click-ui-config.example.js and src/theme/README.md. Added practical examples for Vite, Webpack, Rollup, Next.js, and updated provider/usage docs for new config structure.

Introduces a capitalize function that capitalizes the first letter of a string and converts kebab-case to PascalCase. Includes comprehensive unit tests for various input scenarios.

Updated Container, EllipsisContent, GridContainer, Link, and Text components to use shared polymorphic types from utils/polymorphic for improved type safety and flexibility. Replaced manual capitalization logic with a shared capitalize utility. Adjusted SvgImageElement to wrap SVG in a div for consistent styling.

Updated css-generator utilities to handle arrays, generating indexed CSS variables for array elements. Extended NestedJSONObject and ConfigThemeValues types to support arrays and booleans. Added comprehensive tests for array and nested value handling in CSS variable generation.

Updated Icon.module.scss to apply sizing classes to the wrapper instead of SVG, ensuring SVGs inherit dimensions. Added the disableDefaultSize prop to Icon, allowing consumers to prevent default size classes for custom sizing via className. Updated Icon.tsx and types.ts accordingly, and refactored imports in Icon.stories.tsx for consistency.

Moved common styles for FileUpload components into a new FileUploadCommon.module.scss file. Updated FileUpload.tsx and FileMultiUpload.tsx to import and use shared classes, reducing duplication and improving maintainability. Component-specific SCSS files now only contain unique styles.

Introduces new SCSS mixins for empty and base button styles, refactors components to use these mixins, and removes redundant EmptyButton usage in favor of native buttons. Updates color variable references for consistency, improves icon sizing and specificity, and streamlines theme handling in CodeBlock and chart color stories. Also fixes minor logic and style issues in Card, Collapsible, Popover, and VerticalStepper components.

Removed all files related to the bundler plugin system and configuration architecture, including config plugins for Vite, Webpack, Rollup, and Next.js. Added a new CLI workflow for theme generation: users now create a config file, generate custom theme CSS via the CLI, and import the CSS directly in their app. Introduced new CLI commands and utilities for config loading and CSS generation, and updated documentation to reflect the new workflow.

Deleted example files for App, Next.js, Rollup, Vite, and Webpack from the examples directory. This cleanup removes sample usage and configuration code for Click UI integrations.

Deleted vite-plugin TypeScript, JavaScript, and type definition files. This removes the Click UI Vite plugin implementation and its type declarations from the project.

Introduces a generated cui-default-theme.css file for Click UI, supporting automatic light/dark theme switching. Adds new utilities for CSS building and theme attribute management, removes the old css-generator test, and refactors theme provider and utility files to use the new CSS builder approach. Updates theme tokens and documentation to align with the new system.

Replaces inline chart color rendering in chartColors.stories.tsx with a ChartColorComponent and removes the now-unused chartColors.stories.module.scss file. Also cleans up comments and unused code in App.tsx.

Introduces src/styles/cui.css as a combined entrypoint for default theme and component styles, updating documentation to recommend its use. Adds _cui-variants.scss with modern variant mixins, and extends _mixins.scss with new helpers for full-width, sidebar, form, input, menu item, and SVG styling. Updates build-tokens.js to always use objects in setWith, and adjusts Vite config to output cui-components.css instead of style.css.

Expanded the README and Introduction.mdx with detailed instructions for custom theming using the Click UI CLI, clarified style import options, and explained the build-time CSS approach. Updated references to new CSS entry points and improved documentation on theme switching and CSS variable usage.
