Switching the sidecar on learn.halkyon.eu's server recreated the server
beside LanguageTool, whose start takes a minute: the server's first look
at the languages failed, and it looked again only an hour later, as
after one that worked. Until then instance.info() named no languages,
and an app that asked meanwhile keeps that answer, so its editors check
nothing until it starts anew. A look LanguageTool doesn't answer is now
tried again a minute later, by a timer, until it answers, the languages
known before kept meanwhile; one that worked still counts for an hour.
The server's tests take fake_async (^1.3.3, as Learn's app, already in
the lock) for the timer.

compose.languagetool.yaml runs LanguageTool's open-source server
(meyay/languagetool 6.8-13, pinned by digest) on `edge` with no site and
no published port, as user 61081 on a read-only filesystem, without a
log. The server alone reaches it (LANGUAGETOOL_URL): grammar.check is
for those signed in, takes 20,000 characters, 60 checks a minute each
(counted in memory), maps a studyset's language to LanguageTool's code
and keeps nothing. instance.info() names the languages it checks; the
privacy page says what goes there. sidecars/README.md has the steps.
