+//! AUR search via yay — graphical discovery for the wider AUR beyond
+//! bakery's bread ecosystem and [breadway]'s own republished packages.
+//!
+//! Search and browsing are fully graphical; actually installing a package
+//! opens a terminal running `yay -S <pkg>` instead of a silent `--noconfirm`
+//! install. That's deliberate, not a shortcut we didn't get around to:
+//! AUR packages run arbitrary maintainer-supplied build scripts, and yay's
+//! interactive PKGBUILD diff review (plus the sudo password prompt) is the
+//! actual safety mechanism against a malicious/compromised AUR package —
+//! automating it away in the name of "no terminal" would remove the one
+//! step that exists to catch that.
