/* The hidden attribute is how main.js shows/hides the login vs the
   app shell. Default user-agent `[hidden] { display: none }` loses
   the cascade fight with our explicit `.login-shell { display: grid }`
   and `.app-shell { display: grid }` rules below, so we pin it
   globally. Same fix the mini-app made in commit b035aca. */
