   public-shared.css
   Shared tokens, nav, footer, buttons, and scroll-animation primitives used
   by all public marketing pages (welcome, pricing, enterprise, contact,
   security, blog). Loaded AFTER design-tokens.css.

   The marketing mockups use short token names (--teal, --bg, --t1, etc.).
   This file bridges them to the canonical --color-* tokens in
   design-tokens.css so the mockups work unchanged while the rest of the
   app keeps using the long names.
