Slack Style Chat Block for Svelte

The channel list and the log swap to that workspace's own, and the last channel you had open in it comes back. Every workspace has its own people and typed channels, about four messages each, so the whole data is small and typed in the file.

They are derived from the typed messages: a channel's count is its messages not from you while it is unread, and a tile's count is how many of its channels hold unread messages. Opening a channel clears its count and the tile's follows.

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. Posting adds a flat row to the open channel only. 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 rail becomes a Workspace select above the channel list, a channel opens as a full pane, and a Back button in its top bar returns to the list. The window keeps its height.
