/* ==========================================================================================
   Compass Afar -- marketing site (v3). Plain CSS, no build step.
   Colours, fonts, radii and shadows are copied from the app's frontend/theme.css so the site and
   the app read as one brand. If the app's palette changes, change the tokens below to match.
   Motion is transform / opacity (one exception: the entry wordmark's blur-to-sharp), and all of
   it is switched off under prefers-reduced-motion (the block at the end of this file).
   This file's name carries a version: see the note in index.html before changing it.
