/* Health Sync — public site stylesheet.
   Covers the marketing landing page and the legal pages. It deliberately reuses
   the design tokens from web/src/styles.css (the signed-in console) so the
   public page and the app read as one product.

   Only Bootstrap 5.3 + this file are needed: the public pages ship no jQuery and
   no third-party theme, so there is nothing to build and nothing to fetch from
   another origin. */
