/* Defensive: without this, the [hidden] attribute used by main.js to hide
   the topbar/tabbar/install-banner while logged out is silently overridden
   by the unconditional `display: flex` rules below (author CSS always beats
   the UA stylesheet's own `[hidden] { display: none }`, no matter the
   source order) -- so those elements stayed visibly on-screen even when
   JS had just set `.hidden = true`. Found while capturing the app
   walkthrough screenshots: the login page was showing a live "Log out"
   button and the install banner from a stale/logged-out state. */
