/* GammaWork — design tokens
   v0.8 IM-workbench skin. Light palette only; dark/terminal themes removed.
   Token names match the dark-era schema (--bg-0..4, --fg-0..3, --line-1..3,
   --accent, --pos/neg) so existing component CSS picks up the new look
   without per-file rewrites. New prototype-specific tokens are added below.
