Pick a topic on a lesson's note and it pushes to that topic's collection
in a self-hosted Outline instance when you leave the page; notes without a
topic stay local-only. Settings gets a new Outline Integration card
(URL/token, Save, Test Connection).
Credential handling: the API token lives in its own outline_config.json
in DATA_DIR, deliberately kept out of the general settings flow (GET
/api/settings is fetched on every page load by theme.js - no place for a
secret to ride along). GET /api/outline/config only ever returns whether
it's configured, never the token itself.
The topic chooser reflects Outline's live collection list rather than a
locally cached copy, and resolves a newly-typed topic name to a real
collection immediately (find-by-name-or-create) rather than waiting until
the note is pushed. That's not just an optimization: the push itself fires
via navigator.sendBeacon() on pagehide, which can't read a response, so a
page that fires pagehide more than once for the same load (a back/forward-
cache restore, for instance) would otherwise re-send the same "create a
new topic" intent every time and spawn duplicate collections. Verified
live against a local mock Outline server that firing pagehide repeatedly
for the same lesson creates the collection/document once and updates
thereafter.
