/* ===========================================================================
   docs.shabinder.in — shared theme
   ---------------------------------------------------------------------------
   This file is the single source of visual truth for the site AND for every
   self-contained artifact published into it.

   An agent publishing an artifact links this file and then styles against the
   tokens below. The artifact keeps its own layout and its own components; it
   inherits palette, type and spacing. That is the deal: consistent identity,
   no re-templating of authored work.

       <link rel="stylesheet" href="/theme/theme.css">

   Tokens are defined once on :root (light), then redefined for dark under both
   the system preference and an explicit [data-theme] stamp, so a page renders
   correctly in all three viewer states: explicit light, explicit dark, and the
   un-stamped default that follows the OS.
