   Dark by default, light on request, both driven from the same token set.
   Colour is reserved for meaning: one amber signal for interaction, and the
   severity hues only ever describe severity. No gradient fills on text, no
   blur panels, no glow — the hierarchy comes from type scale and hairlines.
