+-- Key repeat. Repeat is synthesized by the compositor (wl_keyboard.repeat_info
+-- -> the client repeats locally), so this costs nothing on the wireless link.
+-- Omarchy's 250ms / 40Hz already beats Hyprland's 600 / 25; tighten it further
+-- so held keys (backspace, arrows, vim motions) start and stream sooner.

+-- Everything else in the keystroke path was checked and is already optimal for
+-- the Pilot W-Corne (55d4:0461, Vial/QMK over a 2.4GHz dongle): the dongle
+-- advertises bInterval=1 (1000Hz polling), udev pins power/control=on (no USB
+-- autosuspend), nothing polls its raw-HID interface, WiFi sits on 5GHz, and
+-- render:new_render_scheduling is off (no triple-buffer frame of latency).
+-- Remaining latency is the 60Hz Studio Display refresh and the fcitx5
+-- input-method hop (see omarchy-fcitx5.service), neither of which is an
