/**
 * OpenStation — Solo window rendering mode.
 *
 * One window, no desk. Loaded only on a `?openstation_solo=` request
 * (see `includes/solo-window.php`); a normal shell never downloads it.
 *
 * ## What this sheet does NOT do
 *
 * It does not build a second, simpler window. Every rule here hides a
 * surface or removes a decoration — the window itself is the same
 * `.os-window` the desktop paints, wearing the same theme, running the
 * same render callback, carrying the same title-bar buttons its plugin
 * registered. That is the whole point of solo mode: what the user gets
 * is the window they already had, not a lookalike of it.
 *
 * ## What this sheet leaves alone
 *
 * The title bar. Solo mode is generic — an embed or a kiosk keeps its
 * title bar, because nothing else on the page offers a way to move,
 * close or identify the window. An embedder that supplies its own
 * chrome (the native desktop host does; the OS frame is real chrome
 * with real traffic lights) layers its own sheet on top and takes ours
 * away there. Doing that here would leave the generic case chromeless
 * and stranded.

/*
 * Kill the desk. Wallpaper, dock, icon rail, widgets, Mio, sticky
 * notes: all of them are the *desktop*, and in solo mode there isn't
 * one. `display: none` rather than `visibility` so nothing keeps a

 * `.os-files-layer` instead, and Spatial is what a stock install
 * actually shows. Missing it left the rail painted under every solo
 * window — invisible while a window covered it, a flash on every boot
 * before one landed, and fully on show when the requested window did
 * not exist. It also kept exactly the three things the `display: none`
 * above is chosen to deny: a layout box, animation frames, and live

 * The admin bar goes too. It is the desk's chrome, not the window's:

 * clean out of the window it was given.
 *
 * `html.wp-toolbar` carries a `padding-top` for a bar that is no
 * longer painted, and plugins position UI against
 * `--wp-admin--admin-bar--height`; both are rebound to zero so the
 * window's own chrome math resolves against what is actually there.
