PathOfPriceCheck.iss

; Windows installer for PathOfPriceCheck. Built by .github/workflows/release.yml; see
; ../docs/updater.md for why this exists at all and how the updater leans on it.
;
; Per-user by design. %LOCALAPPDATA%\Programs needs no elevation to install to and none to
; write to afterwards, which is the whole point: an install the user cannot write is an install
; the updater can only ever *offer* to update. The portable .zip keeps that degraded path, and
; is the honest answer for someone who wants a folder they can move.
