+# Tablet mode support for 2-in-1 convertibles (currently wired to the
+# ThinkPad X1 Yoga Gen 6).
+#
+# In tablet mode (screen folded flat behind the keyboard) the display should
+# follow the device orientation and an on-screen keyboard should appear when a
+# text field is focused. This module provides that in three pieces:
+#
+#   1. The NixOS half (here): grants petere membership of the `input` group so
+#      the user-level daemon can read the tablet-mode evdev switch
+#      (/dev/input/event17, "Intel HID switches", SW_TABLET_MODE), and wires
+#      in the home-manager module (hyprland-tablet.nix) via sharedModules.
+#
+#   2. A user-level Python daemon (`hyprland-tablet` daemon) that:
+#        - watches SW_TABLET_MODE via python-evdev;
+#        - parses `monitor-sensor` output for accelerometer orientation
+#          (iio-sensor-proxy, already running on this host);
+#        - applies `transform` to the eDP-1 monitor (and matching per-device
+#          transforms for touch/tablet inputs) via hyprctl;
+#        - starts/stops `wvkbd --auto` so a virtual keyboard shows when a text
+#          input is focused while in tablet mode.
+#
+#   3. A `hyprland-tablet` CLI (status / keyboard toggle) used by the
+#      QuickShell bar chip and the SUPER+CTRL+K keybind.
+#
+# Why not iio-hyprland? It rotates on every accelerometer reading regardless
+# of tablet mode; this host's iio-sensor-proxy build has no hinge support, so
+# orientation must be gated on the SW_TABLET_MODE switch ourselves.
