/* Work (shared/chat/work/view.js; docs/work-extension-contract.md §6.2): the
   timeline's steps, approvals, notices and divider, the plan card above the
   composer, the gates (the Plus lock, Add Lumio to Chrome, access: a card in
   a new task, a bar in the composer's place under a task), the approval-mode
   menu, the larger screenshot and the confirmation (docs/design-system.md
   §6.8, §6.9, §6.12–§6.14). A new task is centered like a new chat (chat.css's
   .lc-fresh and .lc-ideas-slot). The view
   is built from chat.css's classes (lc-root, lc-thread, lc-composer, lc-chip,
   lc-send, lc-md, lc-bubble, lc-notice, lc-empty…); these are its own. Every
   class is lc-, every color a theme.css token. Loaded by /chat and Lumio for
   Chrome's side panel. */
