/* Slevin Mail: sign-up / sign-in / recovery page on the account origin (/mail-authorize).
   Modelled on how large mail services build sign-in in 2026 (Proton, Fastmail): the brand colour fills the page,
   a logo bar on top, one confident white card in the middle, nothing else around it. Inside the card: a big heading,
   labelled fields, one full-width primary button, a switch line. Postal blue is ours. */
