/* =====================================================================
   landing.css · R32 landing page (VSchat + VisionX, the same file in both repos) · 2026-10-25
   - The page a first-time visitor sees at / before signing in (only when UI_V2_AUTH is on).
   - Tokens only (design-system/tokens): no hex, no rgb(), no colour names. Light + dark via data-theme.
   - Mobile first (390), then 768 / 1080. One message per section, one primary action (Get started).
   - No JS needed: screenshots switch by theme and width with CSS; every image is lazy, so only
     the one that is shown is downloaded (display:none + loading=lazy = never fetched).
