The token card's title row gains the session's cache-hit share in its
right corner — the harness chat line's own reads-over-billed formula,
reusing the stats board's label and tooltip — hidden until something
was billed. The timing card's throughput chip drops its pill chrome and
bold weight, now reading 输出速度 N tok/s (zh) / TPS N tok/s (en) with
the TPS expansion on the tooltip; both corners share a new plain-text
.lc-card-rate style and keep their native-title tooltips.
