# Central definition for attrsOf-based per-user modules (los.homev2)
#
# This module defines los.homev2 with a submodule that includes options
# from all per-user modules. Each module contributes its options via
# the submoduleWith pattern.
#
# Modules are auto-discovered from sibling directories. Each directory
# must contain options.nix and config.nix files.
#
# Usage in host config:
#   imports = [ ../../modules/homev2 ];
#   los.homev2 = {
#     alice = {
#       languages.go.enable = true;
#       sway.enable = true;
#       firefox.enable = true;
#     };
#     bob = {
#       languages.rust.enable = true;
#       git.enable = true;
#     };
#   };
