/**
 * The notices the HUD's rail shows, edited without a release.
 *
 * The slides used to be compiled into the SDK, so changing a sentence meant shipping a version. The
 * daemon now fetches a small JSON file from our own site, keeps the entries that apply to this
 * machine, and pushes them to the HUD in the impact snapshot. The page never fetches it: the HUD runs
 * inside somebody else's app, whose Content-Security-Policy may forbid the request.
 *
 * Everything here is pure. Fetching and caching live in the daemon; the clock arrives as an argument.
