 Writer's leaf header — THE one app header, owned by the leaf, SHAPED by the
   shared contract: the row is `.stx-app-header` (scitex-ui, css/app/app-header.css
   — linked below, the same way scitex-ui's own `_project_picker.html` links its
   stylesheet). Identity (title + version) on the left, the canonical
   project-selector slot, then the actions slot. Writer no longer carries a
   second definition of that row: the leaf owns the VALUES and the host
   contract, the SDK owns the chrome, so a user sees the same header in every
   app and the phone rules have one place to change.

   Included by editor.html (standalone) and available to a host that mounts this
   app, INSTEAD OF a bare `writer/_project_picker.html` include: one header, one
   title, one version, one picker, whichever side renders it.

   Contract, so a host does not have to know writer's internals:
     * identity  — `Writer` (manifest `label`) + the LEAF package version, never
                   the host's own version. This is a writer header that a host
                   sheds light on, not a host header a writer writes into.
     * picker    — `.stx-app-header__slot--project-selector`, between identity
                   and actions, exactly as scitex-ui specifies. The slot renders
                   the leaf picker ONLY when the host registered the
                   `scitex_project_picker` tag library (see
                   `views._project_picker_available`), because `{% load %}`ing a
                   library that is not installed is a hard TemplateSyntaxError:
                   standalone `scitex-writer gui` serves no projects.
     * actions   — `.stx-app-header__actions`, EMPTY on purpose. Writer's app
                   actions (Compile / Save / Log) live in the editor's own
                   toolbar, which already knows their state; a second set here
                   would be a second source of truth for the same buttons.

   Set `app_header_rendered=True` in the template context when a host renders
   its own header and includes this one: editor.html then skips it and the page
   keeps exactly one header.
