-- Machine profile selection.
--
-- Each profile owns the two things that genuinely differ between machines:
-- the monitor layout and the workspace-to-monitor assignment.
--
-- Selection order:
--   1. $HYPR_PROFILE, if set  (e.g. `HYPR_PROFILE=laptop Hyprland`)
--   2. hostname match
--   3. fallback: "laptop"
--
-- To add a machine: create configs/profiles/<name>.lua and add it to `byHost`.
