/* ============================================================================
   Toloka Gopher TSR — Landing page styles
   ----------------------------------------------------------------------------
   Full-page styling for landing.html. Realizes the approved Claude-design layout
   in clean, token-driven CSS. The hero shell lives in hero.css; this file adds
   the hero CTA/micro and every other section.

   Colours come from tokens.css. A few values in the approved design are NOT in
   the Toloka token set — they are centralized here as --x-* so the Webflow
   rebuild can reconcile them in one place (see DESIGN-REVIEW.md).
   ========================================================================== */

  /* design extras (not yet Toloka tokens — reconcile at Webflow port) */
  --x-tint-1: #e5e5fa;   /* lavender — step/who card 1 */
  --x-tint-2: #e8ffa6;   /* lime     — step/who card 2 */

  --x-tint-4: var(--color-accent); /* yellow — step card 4 */
