  motion · medium cost · respects reduced motion

  Collapsible reasoning trace: the label shimmers 'Thinking' only while isStreaming, then settles to 'Thought for 3.2s' (measured, or pass duration) and auto-collapses — until the user toggles it, after which it stops deciding for them. Muted-foreground chrome, inherits the theme; no shimmer under reduced motion.
