/* ============================================================================
   SLK Platform — Front page (landing) — "SLK Platform Landing" design.
   Self-contained, theme-aware restyle of #landing. Scoped under `.landing`,
   every class prefixed `nl-`. Fonts use the platform tokens (--sans / --mono);
   the product's own security posture is same-origin, so NO external font CDN.
   Light is the design's native look; a dark variant flips the nl-* tokens.
