/* ==========================================================================
   AUTH-SCREENS.CSS — sign-in / sign-up form, in the landing design system.
   Requires brand-tokens.css. Used by login.html, the auth modal on
   landing.html, and auth-confirm.html.

   What the landing page dictates (screen 9a of the design file):
   Fraunces for the heading at weight 500; 2px corners everywhere; the
   primary button is white (the text colour on ink), turning green on
   hover; hairline dividers; NO gradients, no glow; labels are eyebrows —
   10.5px, uppercase, letter-spaced. The two brand marks stay in colour:
   Google's brand terms do not allow recolouring the G, and a LinkedIn
   mark in the wrong blue reads as a knock-off.

   Room to read: 54px targets, 16px inputs, 26px between groups (2a).
