/*
 * Persistent bottom navigation — final contract.
 *
 * Loaded after every other stylesheet. Older layers hid the bar whenever a
 * view flagged "keyboard open" (matrix-keyboard-open, cid-keyboard-input-active).
 * Those flags could stay set after the keyboard closed (for example after
 * tapping "Calculer" in Déchiffrement MT, or after returning from the Google
 * sign-in page), leaving the visitor without any way to leave the screen.
 *
 * The bar now has one rule: it is always on screen, except while the soft
 * keyboard is really visible (html.cid-soft-keyboard-open, measured by
 * bottom-nav-guard.js) or inside the few full-screen workspaces that provide
 * their own close/back control.
