Provider tiles become list rows with an icon chip, description in
maxcontrast and a chevron, with hover and visible focus styles.
Secondary actions (another method, backup code, cancel) are grouped in
one block under a divider with button-like hit areas. The code input
and submit button get a larger, full-width style shared through
.two-factor-code-input and .two-factor-submit, and the backup code
input uses autocomplete="one-time-code".
The setup selection and setup challenge pages use the same classes.
