WhatsApp Style Chat Block for Ark UI

Each wallpaper is a CSS background image built from the border color variable: radial dots, crossed hairlines or diagonal lines, with no gradient fill. The choice is local state and the status line says it stays in this tab; to keep it, store the value with the user's settings.

It is a floated span at the bubble's bottom end, so short messages stay short and long ones wrap around it. Yours say "Sent" until a reply follows, then "Seen"; both are derived words, not ticks or colors.

Everything. The replies come from a short typed script in this file: a few keyed on words in your message, then one fallback per message and a last line that says it was the last sample reply. Each reply is keyed on a word in your message, such as Sunday or pumpkin. Nothing is sent and no model runs, as the line under the composer says. To wire it for real, send the text where the code says so and append incoming messages to the same list.

The log is a focusable region announced as a log, so new messages are read out once, and every message starts with a hidden sender and time. Receipts and states are a glyph and a word, never a color. Tab runs through the controls, the field and Send.

The same single column. The wallpaper select stays in the top bar, the bubbles take most of the width and the window keeps its height with only the log scrolling.
