3939 Search (#8823) adds no component class: the form is a `.bar` with `.input` and `.btn`, and the results and the conversations list are `.list` of `row()`s (an "archived" `badge` as the trail, the match as the row's meta). The turn a result opens at is marked by a muted hairline on its left edge, `.talk-turn:target`, the one new rule, which replaces the two `.talk-chats li a` rules the rows made unnecessary.
4040
4141 #9690: the page speaks the home page's language: an `sr-only` h1, the conversations as a `.list` of rows, and no box round a turn, a tool call or a held action; the only hairline is above the composer. No new classes.
42
43 #11009: the builder layout. The pane's tabs are the `.tabs` component and the phone's Chat / Preview switch is `.seg`, both links (`?pane=`) the server draws, so it works with the script off; the pane is parted from the chat by one hairline, no box.
44
45 - `.talk-shell` — the grid holding the chats sidebar, the chat and the preview pane; one column on a phone, where `data-pane` (from `?pane=`) says which shows.
46 - `.talk-side` — the sidebar column wrapping `.talk-chats`.
47 - `.talk-tabs` — the phone-only Chat / Preview `.seg`.
48 - `.talk-pane` — the right pane: one head line (repository · pull or Production · Open on its own), `.tabs`, then the chosen panel; its left hairline is the only rule.
49 - `.talk-frame` — the framed live preview, no border.
50 - `.talk-step` — a tool call drawn as one closed line; opened, its `key: value` lines, one per line, in the tool card's plain paragraph.

1 # Talk as a builder (#11009)
2
3 `/talk` is two panes on a wide screen: the chat (with the chats sidebar), and on the right the live preview of the repository the chat is working on, with Code and Diff beside it. Preview, Code, Diff and, on a phone, Chat / Preview are plain links (`?pane=`) drawn by the server, so all of it works with the script off; with the script a tab swaps the pane in place, so a streaming reply and the composer's words are kept.

Both doors: Code and Diff have no terminal equivalent. Add them to the Talk screen rather than document the gap.
4
5 The terminal has the same: the Talk screen (`src/tui/screens/talk_chats.ts`) draws the same steps, names the repository in its header, and `p` flips to the pane's contents: the repository and its pull, the address of what runs (Preview), the pull's files page (Diff) and the files the chat touched (Code). Both read `src/actions/talk_workspace.ts`. A terminal cannot draw a web page, so it prints the preview's address instead of framing it.
6
7 - **Which repository:** the last one a tool call in the conversation named (`src/core/talk_steps.ts` `repoOf`), shown only if you can read it.
8 - **Preview:** the newest open pull's preview environment, else production, framed from the app's own origin (the page lists that one origin in `frame-src`; `originOf` takes scheme, host and port only, so a URL with userinfo names none). It reloads when a turn ends, which is when a push has deployed. Code lists the files the chat touched; Diff links the pull's files page (not frameable).
9 - **Steps, not JSON:** each tool call is one line ("Read src/a.ts", "Edited src/a.ts (+12)", "Opened pull #12", "Merged pull #12 and deployed"), closed; its `key: value` details open on a tap. Raw JSON is never drawn. The line under a reply summarises ("Read 4 files, opened #12").
10 - **Stop and Steer** while a reply streams, and the context meter, are unchanged.
11
12 Not yet: sidebar grouping by repository (a chat has no repo of its own), added/removed counts on edits (stored calls are cut short; only added lines are known), per-turn versions to go back to.

22 * The /talk page's own stylesheet and script (#7652), kept apart from the

6 * Why the script is shaped as it is (kept here, out of the bytes it ships):
7 * - Copy buttons are drawn by the script, not the server: without the script
8 * they would do nothing.

Principle 3/6 and the byte cap: 600 extra CSS bytes for layout. Trim or justify; the cap was raised to fit rather than the code trimmed.
