#
# Debian package build for PostIt (Yavsc desktop client).
#
# Pipeline:
#   1. Clone pazof/yavsc at POSTIT_GIT_TAG into a clean working
#      tree under build/yavsc-src.
#   2. dotnet publish src/PostIt/PostIt.Desktop — framework-
#      dependent (not self-contained), into build/postit-app.
#   3. Render the icon at the hicolor sizes from
#      src/PostIt/PostIt/Assets/Icon.png, plus the SVG as the
#      scalable form.
#   4. Stage everything under debian/tmp/ — the layout dh_install
#      expects:
#         /usr/lib/postit/           (managed assemblies)
#         /usr/bin/postit            (wrapper script)
#         /usr/share/applications/   (postit.desktop)
#         /usr/share/icons/hicolor/  (icons)
#   5. dh_install moves it all into debian/postit/ and the rest
#      of the dh_* helpers assemble the .deb.
