/* Mercurium websites: the ONE shared look of mercurium-analytics.ai and the Mercurium Data site.
   Owned by the public website (public/), linked by both sites. Values are the Data app's light theme
   (static/css/mercuriumdata.css) and the logo's blues: the Mercurium font, white cards on the light grey
   page, hairline borders, the dark primary button. Very rounded rectangles, never pills; no gradients,
   no glow, no purple.
   Served through the app's asset view (home:home_v2_asset 'mercurium-site.css'), so the font addresses
   are absolute: the static host is the same on every environment. */
