[Feature] Add Message component - #446

Conversation
Port the shadcn Bubble component: a chat bubble surface with 7 variants (default, secondary, muted, tinted, outline, ghost, destructive), start/end alignment, grouping, and edge-anchored reactions. - Translates shadcn's cn-bubble-* CSS layer to real Tailwind v4 utilities and RubyUI theme tokens (no custom CSS shipped). - BubbleContent is polymorphic via as: (:div/:a/:button) for link/button bubbles — the idiomatic Phlex equivalent of shadcn's asChild. - No JS. Composes with Tooltip/Popover (docs examples included). Docs page, route, controller, menu entry and site_files updated.

Built on top of Bubble (#445). - 6 parts: Message (align start/end), MessageGroup, MessageAvatar, MessageContent, MessageHeader, MessageFooter. - Reuses the existing Avatar and the new Bubble components — no new primitives. Bubble alignment inside a message is driven by Message via group-data-[align=end]/message; Bubble itself is unchanged. - Translates shadcn's cn-message-* CSS layer to Tailwind v4 utilities. - dependencies.yml: message depends on Avatar + Bubble. Closes#444. Docs page, route, controller, menu entry and site_files updated.

Port the shadcn Message Scroller: a chat transcript scroller that follows the live edge, anchors new turns near the top, and jumps to the latest message. Built on top of Message (#446) and Bubble (#445). shadcn delegates to a closed React primitive (@shadcn/react); this is a from-scratch Stimulus controller (ruby-ui--message-scroller) — our own code, no external lib: - autoScroll follow-edge: pins to the bottom while the reader is there, releases on wheel/touch/keyboard/scrollbar away, re-engages on jump. - scrollAnchor: settles an appended turn near the top keeping a peek of the previous item (previous_item_peek). - defaultPosition: open at end / start / last-anchor. - preserveOnPrepend: hold the visible row when history loads in above. - Public API for streaming/ActionCable: scrollToEnd/scrollToStart/ scrollToMessage; new rows are picked up via MutationObserver. - rAF-based smooth scrolling (native smooth is unreliable on a contained viewport), honors prefers-reduced-motion. - a11y: content role=log + aria-relevant, button sr-only label, button removed from tab order while inert. Parts: MessageScrollerProvider, MessageScroller, MessageScrollerViewport, MessageScrollerContent, MessageScrollerItem, MessageScrollerButton. dependencies.yml: message_scroller depends on Message + Bubble. MCP registry, docs page, route, controller, menu and site_files updated.

* [Feature] Add Empty component Port the shadcn Empty component: a centered empty-state surface for when there is no data or content. Parts: Empty, EmptyHeader, EmptyMedia (default/icon variants), EmptyTitle, EmptyDescription, EmptyContent. Translates shadcn's cn-empty-* CSS layer to Tailwind v4 utilities. No JS. Docs page, route, controller, menu, site_files and MCP registry updated. * [Feature] Add Message Scroller component Port the shadcn Message Scroller: a chat transcript scroller that follows the live edge, anchors new turns near the top, and jumps to the latest message.

Rebuilt MCP registry. * [Documentation] Message Scroller: faithful chat-window demo with Empty state Add the shadcn-style chat window as the hero example: a Card with an Empty state until the first message, then a scrolling transcript that follows the live edge, plus an input footer. A docs-only Stimulus demo harness (message-scroller-chat) clones server-rendered user/assistant templates on send so the scroller's autoscroll/anchoring is demonstrated live — standing in for a real ActionCable/streaming source. Uses the new Empty component. * [Bug Fix] Message Scroller: direction-aware scroll button visibility updateButton now derives each button's active state from its own data-direction — an end button activates when away from the bottom, a start button when away from the top — and iterates all button targets. Previously a start-direction button used end logic, so it was inert at the live edge and showed at the wrong end. (cubic P2)

What's included
Message— row container,align:(start/end); flips avatar/content viaflex-row-reverseMessageGroup— stacks messagesMessageAvatar— wraps the existingAvatar; anchors to the row bottom and lifts when a footer is presentMessageContent— column holding bubbles; drives bubble alignment viagroup-data-[align=end]/messageMessageHeader/MessageFooter— muted meta lines (name, timestamp, "Delivered")Reuse — no new primitives
MessageAvatarMessageContentBubble alignment inside a message is handled entirely by Message — Bubble is unchanged.
dependencies.yml:messagedepends onAvatar+Bubble.Notes
cn-message-*CSS layer; this port translates every rule to Tailwind v4 utilities. No custom CSS, no JS.Marker(the "is typing…" indicator) is a separate shadcn component, out of scope here; the demo uses plain footer text instead.Testing
