docs/hid.md claimed VT byte 23 (ETB / Ctrl+W) maps to `ctrl-bksp`, in both the byte→event table and the Control Byte Collisions table. The VT code keeps the Ctrl+letter identity and emits `ctrl-w` (hid.sh: 1..26 → ctrl-<letter+96>); the `ctrl-bksp` remap for byte 23 exists only in kitty "func" mode (hid.sh:389). Correct both rows to `ctrl-w` and reword the prose to explain that on terminals which send 23 for Ctrl+Backspace it also surfaces as `ctrl-w` in VT, and to use the kitty protocol to disambiguate. Verified: _tuish_resolve_event "E 23" → ctrl-w, "E 8" → ctrl-bksp. docs/tui.md listed the kitty keyboard (ESC[>9u) in the "configured at startup" table, but tuish_init never sends it and TUISH_PROTOCOL defaults to vt. Remove that row and add a note that kitty mode is opt-in via tuish_kitty_on (probed, with VT fallback) and restored by tuish_kitty_off / tuish_fini.
