   Stand-alone app stylesheet for ai-for-executive-assistants.html.

   This page is an application, not an article, so it deliberately
   does not inherit css/style.css. The visual language is Apple's:
   system typography, generous rounding, hairline separators, soft
   elevation, frosted chrome, and motion with a single easing curve.
   Light and dark are both supported through prefers-color-scheme.

   Two print modes, chosen by a data-print attribute the script sets

     "cert"   the certificate on its own
     "canvas" the single canvas marked .is-printing
   With no attribute set, printing falls back to the certificate,
   which is what a reader pressing Ctrl+P on this page expects.
