/* auth.css — shared styling for the authentication gateway pages
   (login / register / reset-password).

   One cohesive "current brand" look: the product's radial gradient as a
   full-bleed backdrop, a single elevated white card holding the form, the
   brand blue (#3d647f) for primary actions and the mint accent (#03dac6) as a
   highlight. Self-contained on purpose — these pages are the front door, so
   they don't inherit the app's 80%-density base.css; they read at a
   comfortable, modern scale instead. */
