/* ==========================================================================
   Catlist — design system, v3 "Midnight"
   --------------------------------------------------------------------------
   Every colour, size, radius and curve in the product is declared ONCE here,
   for two themes: Midnight (the default, :root) and Daylight
   ([data-theme="light"], set by theme.js before the page paints). Pages
   compose primitives and read tokens; a hex in a page is a bug.

   The look: a deep midnight ground with two soft glows, glass cards with a
   hairline border, one blue -> sky -> aqua gradient for everything that is the
   next thing to do, and a small set of state colours that each mean one thing:
     emerald = ready / done        amber  = draft / look again
     rose    = blocked / failed    sky    = information
     violet  = handled, stopped on purpose (a wrong page we refused)

   Fonts are served from /static/fonts (Inter for text, Space Grotesk for
   headings and numbers). Nothing is fetched from another server.

   WHY THIS FILE IS IN A CASCADE LAYER — do not remove the wrapper.
   The marketing pages keep their own systems in later layers (landing.html:
   sl-fallback, sl-page) or unlayered (pricing, request, login). Declaring
   `shelfline` first makes it the WEAKEST layer: this file is the floor a page
   stands on, never a lid on top of it. A page's own rules always win.
