Subject: [PATCH] TrendingLexicons: chat.bsky out of trending, chat.* out of
 top, schema link, microcosm credit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three small refinements:

1. Hidden-prefix lists per mode:
     - Trending hides app.bsky.* AND chat.bsky.* (both Bluesky flavors).
     - Top hides chat.* (private DM traffic isn't a fair "what's hot"
       signal). Bluesky public namespace stays in Top — it's the
       elephant in the room and that's accurate to show.

2. Clicking a row now opens the lexicon's schema record on its
   publisher, not the explorer's collection view. Convention: NSID
   `<tld>.<owner>.<...>` maps to publisher `<owner>.<tld>`, so
   `net.anisota.foo` -> `anisota.net`. Deep link goes to the
   explorer's record page at
   `/explore/<publisher>/com.atproto.lexicon.schema/<nsid>` and
   reuses RecordPreview to render the schema doc. Falls through to
   the explorer's not-found UI when the publisher hasn't published
   one — acceptable fallback.

3. Small microcosm credit row at the bottom of the card:
   "Data from microcosm.blue". UFOs is theirs; surface the
   attribution.
