Hovering a legend row or a ring segment now lights both: the shared
hover key dims the other slices to the stacked bars' 0.35 idiom and
tints the active row. A hover with no painted arc (a zero slice) tints
the row but leaves the ring at rest. The legend names bolden, and the
token buckets get clearer names and colors: Cached Input / 缓存输入,
Uncached Input / 未缓存输入 (violet, no longer blue-next-to-blue with
Output), Cache Hit, Cache Write.
