   landing.css — the tirolog.app front page (store/index.html)

   Mobile first; from 900px wide each block puts text and picture side by
   side. Colours, radii and type follow the app (css/main/design-tokens.css):
   the landing only exists in the app's dark look, which is the brand's.
   ⛔ Nothing is loaded from another domain (tests/unit-landing.test.js): the
   type is the app's (Oswald and Inter), served from store/fonts/.
   Motion is decoration only and stops under prefers-reduced-motion.
