   Every rule is scoped to a class. The first version of this file styled
   `main` directly for the app shell, and that rule also matched the sign-in
   page's <main class="sign-in-card"> — `flex: 1` sets flex-basis: 0, which
   beats a width of 380px, so the sign-in card rendered the full width of the
   screen. A bare element selector is a rule with no idea which page it is on.

   Right-to-left comes from logical properties (inline-start/end, margin-inline)
   rather than left/right, so the same stylesheet lays out Arabic and English.
