/* shell.css ─ root document + app shell primitives.
 *
 * Defines the html/body baseline AND the .wd-shell horizontal layout
 * (sidebar + main pane). Every authenticated app page mounts inside
 * .wd-shell; this is the only correct way to lay out the app.
 *
 * History: pre-shell.css, each page rolled its own
 *   body { margin: 0; } .wd-shell { display: flex; min-height: 100vh; }
 * inline. Pages that forgot rendered with the sidebar stacking on top
 * of the content (8px default body margin + display:block .wd-shell),
 * which read as "dead space at top, left-shifted content at bottom".
 * Codifying it here prevents that footgun.
