Subject: [PATCH] refactor(client): drop the Context Trend card's subtitle hint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "✂ marks compaction/prune, Step/Turn switches granularity" caption
restated controls that are already visible in the card's own title row,
so it only crowded the header. The subtitle span now renders solely for
the transient focus state ("Showing {cat} only"), and the unused
trend.hint key leaves both dictionaries.
