/* TimelyNodes marketing site (the redesigned pages).

   Direction: order out of constraint. A calm, light editorial base for a university and
   enterprise reader, with one dark chapter where the engine and the product are shown.
   The dark tokens are the operator app's (web/src/globals.css), so moving from the site
   into "Try the demo" feels like the same product.

   Rules this file keeps:
   - One accent (teal). Light surfaces use the darker step for text contrast.
   - Radius: cards and frames 14px, buttons and inputs 10px, pills only for tags.
   - Motion lives in shared/site.js. This file only defines end states and the
     no-JS / reduced-motion rendering, which is always complete.

   The research pages (universities.html, wishlist.html) still use styles.css. */
