/* ═══════════════════════════════════════════════════════════════════
   auth_modal.css — sign-up / log-in overlays for the detector surfaces.

   DEFINES NO PALETTE. Every colour is a var() from tokens.css, which is
   loaded on every page that carries this file, so light mode (theme.css
   re-declaring the same names) needs zero work here.

   Class prefix is `am-` on purpose: profile/billing/keys/history/redeem
   already load pages.css, which owns `.modal-*`. Sharing those names
   would silently restyle the password and email dialogs.

   beats the gap and nets -2px, so the hint climbs INTO the code box. Measured:
   hint.top was 2px above input.bottom until this line existed. Let the flex gap
