/* DeepinGEO public product landing page (src/components/portal/landing.tsx).
   Restrained developer-tool aesthetic: neutral gray sections, near-black ink, a single blue
   accent, 1px hairline borders and almost no shadow. The --dg-* tokens and base resets live
   in the shared styles-tokens.css, which the LandingDocument links before this file; the
   lp-* rules below only use the tokens. */
