Subject: Add live album filter search box
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Typing in the search box instantly hides non-matching album cards.
Shown only when an album has more than 4 sub-albums (no point otherwise).
Pure client-side — no server round-trips.
