/* ===========================================================================
   The public surface: landing page and the signed-out account screens.

   Kept out of style.css so that in-app pages — which every signed-in user
   loads on every request — do not carry the marketing page's weight. Both
   files share the design tokens declared in style.css, so a token change still
   moves this surface with the rest of the product.

   Written to work in both writing directions. Anything that would pin an edge
   uses logical properties (margin-inline, inset-inline, border-inline-start),
   so the Arabic interface mirrors correctly instead of needing its own rules.
   =========================================================================== */

/* Declared on :root, not on `.lp`. The account screens carry `.authpage`
   instead, and a variable scoped to `.lp` resolves to nothing there — which
   silently collapsed the sign-in panel's gradient and left white text on a
   white background. */
