/, /all, /search and /category are anyone's to ask for (#215), and each
called Store::list: the whole catalogue, joined with the snapshots and
grouped, on the 10-connection pool the refresher and every server's
/v1 calls share, on the Postgres that holds production ipx's database.
The pages' Cache-Control did nothing for a request with a query string
of its own, such as /search?q=<random>.
Directory::pages_list keeps the list for a minute behind a mutex held
through the read, so a burst of misses waits on one query rather than
each sending its own. Filtering and rendering still happen per request,
in memory. /v1/feeds, behind a token, still reads the database.
