/* ForteFit login / accept-invite / reset — its own stylesheet.
   Deliberately self-contained: NOT an @import of public/styles.css, because
   this page is served anonymously and must not depend on a gated asset.
   Tokens are copied from styles.css so the page matches the app exactly.

   Dark, mobile-first, one-handed. Every tap target >= 44px, every input
   16px (anything smaller makes iOS Safari zoom on focus and the layout
   then scrolls sideways). No horizontal scroll at 375px. */
