/* Foundris landing page. Plain CSS, no build. It uses the Foundris design system: the tokens below are copied from frontend/src/styles/tokens.css with the SAME
   names and values (the dark theme for the page, the light theme for the demonstration sheet, as the app does with data-theme), and the type roles are the
   app's. WwwSiteTests fails if a copied value differs from tokens.css. Landing-only layout values are prefixed --www- and declared after the copied blocks.
   Contrast, WCAG 2.x relative luminance:
     dark theme: ink #eceef1 on surface #111316 16.0:1; ink-muted #a7adb6 8.2:1 (on surface-raised #1a1d21 7.5:1)
                 brand #7fa8f5 (accent text, links) 7.8:1 (on surface-raised 7.1:1); button text on-brand #0a1424 on brand #7fa8f5 7.7:1, on the hover step #a9c6fa 10.7:1
                 line-strong #737a85 (control edge) 4.3:1 (3:1 is needed)
     light theme (the sheet): ink #17191c on surface #f3f2ef 15.7:1; ink-muted #57585a on surface 6.4:1, on white 7.1:1
