/* ════════════════════════════════════════════════════════════════════
   Daem — the site is a workspace.

   The page is not a document that scrolls. It is the same shape as the
   app: a project rail, workspace tabs, a grid of panes, a status bar.
   Sections are workspaces. Paragraphs live in panes.

   One escape hatch: body.plain flattens all of it into a plain
   document. Everything is in the DOM either way, so nothing here is
   load-bearing for reading the site.

/* ═══════════════════════════════════════════════════════════════════════
   Flat mode — the same content as an ordinary document.

   Two ways in. `body.plain` is the reader's choice, from the title bar or
   `?plain`. `html.nojs` is the fallback: app.js clears that class the
   moment it runs, so if it never runs — scripting off, or a policy that
   will not load it — the site is a complete document instead of a shell
   with dead tabs. Both land in the same place, which is the point.
