TsgcHTMLComponent_ChatBox — a card-style chat bubble box with left/right messages, avatars, an input bar and an animated typing indicator, in Delphi, C++ Builder and .NET.
A lightweight chat component that emits a Bootstrap 5 card with scrollable message bubbles and an optional input bar. Add messages, set a few properties, then read the HTML property.

Set the Title and Height, push a few messages with AddMessage (choosing caLeft or caRight), then read HTML (or drop it into a TsgcHTMLTemplate_Bootstrap page).

Messages is a TsgcHTMLChatMessages collection; each TsgcHTMLChatMessage carries Sender, Text, Timestamp, Align (caLeft/caRight), Color and AvatarInitials.
AddMessage(aSender, aText, aAlign, aColor, aTimestamp) appends a bubble; the avatar initials and time are filled in for you when omitted.
ShowInput toggles the form; InputPlaceholder, SendButtonText and SendButtonStyle (a TsgcHTMLButtonStyle) control the composer.
Title sets the card header; ShowTypingIndicator reveals the animated dots and TypingText sets its label.
ChatID names the element ids; Height bounds the scroll area (auto-scrolls to the newest message).
HTML returns the whole card; GetLastMessageHTML returns only the most recent bubble — ideal for pushing a single update over a WebSocket.
