+# Each profile is a special workspace, the monitor it opens on, and its
+# resident apps (class pattern -> launch command; the pattern is an anchored
+# ERE, so a plain class name matches itself). hypr/hyprland.lua pins every
+# class to its workspace, so only the launch and the reveal are left here. A
+# resident is launched only when no window on the workspace matches it, which
+# is what keeps a launcher that always opens a fresh window (the Chromium
+# web apps) from piling up duplicates. On first start the master layout gives
+# the master slot to whichever window appears first (a terminal beats an
+# Electron app); swap them afterwards if the arrangement matters.
+#
+# HOME_MONITOR is a connector name or an EDID description (the latter, as in
+# the workspace rules, survives a different DP connector after re-docking).
+# When it is empty or that monitor is absent, the workspace opens on the
+# focused one.
