An edge that is not drawn, and a panel that stopped eating the site
`hx-get=""` is not "fetch nothing". htmx looks for the attribute, not for a value, so the empty one the canvas rendered before a chat existed was a real request for the empty path -- which the browser resolves against the current document. Opening the canvas on the new-chat screen fetched the new-chat screen and swapped the whole site into the panel. The attribute is omitted now, and a test refuses an empty verb anywhere on the page. Which panels can exist is the server's answer; which are offered is the browser's. Both need an agent chat on a chosen connection, and before a chat exists those are controls in the composer -- so answering with the first profile offered a terminal on an ordinary chat with nothing selected. They follow `lembas:agent-target` now, and an open panel whose target goes away is closed rather than left showing one machine under another's name. `.tabs__body` is only sometimes the scroller: true where the tabs are a bounded flex child, false under the admin layout, where the page scrolls instead. So setting its scrollTop on every tab change had never once run on /admin/prompts, silently, while the reader was dragged to the bottom of a document that had just got shorter. The rule names the position now, and the handler finds the container that actually scrolls. The two top borders come off. They were what made the misalignment at the bottom of the shell visible; `--footer-height` stays, because two ends at different heights are visible without a line to prove it. The top of the shell keeps its line -- there, everything is `--header-height` and aligns by construction. And one version. pyproject carried its own copy and had drifted three minors from the one everything actually reads. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
