# doq host installer — downloads the latest release from get.doq.computer and
# installs it as a login-persistent menu-bar (macOS) / tray (Linux) app.
#
#   curl -fsSL https://get.doq.computer | sh
#
# This script is itself served at https://get.doq.computer/ (the root route),
# alongside the per-platform archives, by the doq-get Worker (../get-worker)
# backed by the private `doq-releases` R2 bucket — so it works without the source
# repo being public.
#
# The macOS app is ad-hoc signed (not notarized). curl-downloaded files aren't
# quarantined, so it launches without the Gatekeeper prompt and asks for Screen
# Recording + Accessibility as "doq" — exactly like a local dev build. See
# docs/auth.md. Re-running upgrades in place; an existing config.json is kept.
