What's new in astro-ui

✚Added

• Foundation: semantic design tokens (tokens.css), base styles (base.css), data-theme light/dark/system theming, cn() and uid() utilities, and root + per-component ESM subpath exports with no runtime dependencies.
• 63 catalog components across 7 categories (80 .astro files including sub-components): 43 render pure server-side HTML and 20 add a small scoped script.
• General (7): Button, ButtonGroup, Command, Carousel, Clipboard, Kbd, Link.
• Data display (10): Badge, Avatar, Attachment, Table, Progress, Bubble, Chart, Empty, Tag, Timeline.
• Layout (7): Card, AspectRatio, ScrollArea, Separator, Accordion, Collapsible, StickySurface.
• Feedback (6): Alert, Spinner, Skeleton, Toast, Banner, NotificationCenter.
• Forms (18): Autocomplete, Combobox, Label, Field, Input, InputGroup, Textarea, Select, Checkbox, Radio, Switch, Toggle, ToggleGroup, RadioGroup, Rating, Slider, DatePicker, TimePicker.
• Navigation (7): Tabs, Breadcrumb, Pagination, Stepper, Tree, Navbar, Sidebar.
• Overlay (8): Dialog, AlertDialog, Sheet, Tooltip, Popover, HoverCard, Lightbox, Menu.
• Native-first interactive behavior: Dialog, AlertDialog, and Sheet on <dialog>; Accordion and Collapsible on <details>; Tabs, Menu, Tree, and Combobox with WAI-ARIA roles and scoped keyboard scripts.
• Shared --ui-control-* scale (height, inline padding, radius) used by Button, Input, Select, Textarea, and InputGroup so controls align on a row.
• Missing semantic tokens: --ui-card, --ui-backdrop, --ui-backdrop-strong, --ui-progress-stripe, --ui-shadow-color, --ui-rating-1…5, --ui-text-3xl, --ui-space-0-5, --ui-space-7, and --ui-transition-delay.
• Docs site (web/): component catalog, per-component pages (props, slots, accessibility, theming, JS cost), live demos, 25 composed blocks, token playground, and guides for theming, styling, RTL, events, and Tailwind.
• Tests: Vitest unit and static component contracts, drift checks for tokens and prop vocabulary, Playwright interaction specs, and Chromium light/dark visual baselines.
• Release tooling: gen-docs (registry → content markdown) and audit-demo-ids (registry ↔ demo wiring check).
• Repo files: README, CONTRIBUTING, SECURITY, LICENSE (MIT).

↻Changed

• The canonical brand color is Astro violet: #881abd light / #b845ed dark, with hover #b845ed / #d06cf5; --ui-ring follows the brand primary in both themes.
• The semantic red prop value is destructive everywhere; the --ui-error* token names are unchanged.
• Button shape accepts rounded | square | circle | pill (default rounded).
• Component-private CSS variables use the --aui-* prefix so they never collide with public --ui-* tokens.
• Keyboard focus uses a :focus-visible outline driven by the focus-ring tokens instead of a box-shadow ring.
• Every component declares since: 0.1.0, the first public release.

◐Fixed

• Dialog, Lightbox, Sheet, and AlertDialog backdrops, Progress stripes, Carousel shadows, and Chart SVG shadows resolve through tokens instead of hard-coded colors.
• ScrollArea exposes a labelled region; LightboxItem accepts captions and captionsLang for video tracks.
• The docs build no longer warns about Astro :global() selectors in the plain stylesheet.
