/* ==========================================================================
   MSG Assistant — curated, rule-based chat widget (no live AI billing)
   The widget is appended directly to <body>, outside any .on-dark/.on-light
   section wrapper, so it must carry its own theme-scoped variable values —
   it cannot rely on inheriting --bg/--fg/--accent/etc. from a parent section.
   Without this block every var() below resolves to nothing, which is why the
   widget previously rendered with a transparent background and unreadable
   text against both black and white page backgrounds.
