/* Foinse signed-in app shell. Item 7-9 of the front-end gap list.
 *
 * One shell, three rails: a left icon rail for the five jobs, a top bar
 * carrying the search field, and a right action rail for the four money
 * moves. Every value resolves through tokens.css; this file adds no color
 * and no type size of its own. The shell is opt-in: a page carries
 * `class="app-shell"` on <body> and the shell renders. Pages that do not
 * carry the class are untouched, so the marketing header survives on the
 * marketing surfaces and disappears only where the shell is on.
