# Default applications per file type -- the single source of truth for "open
# with" across the desktop: xdg-open, file pickers, and Enter in mc (whose
# mc.ext.ini delegates every non-archive type to xdg-open; see mc.nix).
#
# These belong in the public baseline because the handlers do too: zathura, imv
# and mpv come from media.nix, libreoffice from home.nix. So "PDF opens in
# zathura", "images in imv", etc. are the natural defaults of this baseline, not
# personal choices -- every entry is mkDefault, so a consumer overrides one type
# by setting the same key (their definition wins), or flips enable off entirely.
#
# Personal handlers -- web browser, mail -- are NOT here; they map to a specific
# browser profile / mail client and live in the private inventory, merging into
# the same defaultApplications attrset.
