/* ==========================================================================
   Jade Theme for Abismo
   Palette: deep jade greens with a warm brass accent.
   Supports auto / light / dark via the standard token pattern:
     - :root holds the light (default) values.
     - @media (prefers-color-scheme: dark) applies dark values automatically,
       unless the page has been forced to light mode.
     - :root[data-theme="dark"] / [data-theme="light"] let a toggle override
       the OS setting. Wire a switch by running one of:
         document.documentElement.setAttribute('data-theme', 'dark');
         document.documentElement.setAttribute('data-theme', 'light');
         document.documentElement.removeAttribute('data-theme'); // auto
