6 * foot: no header, no sidebar, no rail.
7 * - `app`: someone signed in, everywhere else. The rail, the mode's
8 * sidebar and the page in its panel, always about their current
9 * workspace, even on public pages such as Explore, a profile or another
10 * workspace's public project.
11 * - `public`: a visitor who is not signed in (or has not confirmed their
12 * address yet), on every other page: a plain header with the logo,
13 * Explore, Docs and signing in, the page at full width, and the footer.
