/* trstctl.com — one stylesheet for the landing page, /47days and the docs shell.
   Tokens are the console's own (trstctl/web/src/index.css), stored as bare HSL
   triplets exactly as the product stores them, so the site and the console
   are one design language: warm paper, forest action, mint focus, gold only
   for caution. Light is the default; dark follows the system or the visitor's
   stored choice, which is the same localStorage key the console reads
   ("trstctl-theme"), so the choice carries into the demo. */
