Subject: [PATCH] feat: report key matrix and layer over raw HID for keyglance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enable RAW_ENABLE and send a report on every physical key event (row,
col, pressed) and on layer changes (active layer) via raw_hid_send, so
the keyglance overlay can highlight the exact physical keys pressed —
including while in steno mode, where the steno protocol otherwise hides
which physical keys are down.
  - rules.mk: RAW_ENABLE = yes
  - keymap.c: raw_hid_receive stub, kg_send_key/kg_send_layer helpers,
process_record_user reports real matrix keys (combos/virtual filtered),
layer_state_set_user reports the highest active layer
