/*
 * scan.c - Phase 1 barcode diagnostic: keyboard / scan-key route.
 *
 * A working on-device demo triggers the laser from the keyboard scan key, so
 * the system arms the scanner and delivers the decode via the scan-key path -
 * not via an app-opened TTY:D or BAR: channel (both of which gave us nothing).
 * This build opens NOTHING and simply reads the keyboard, echoing every key
 * code. If the decoded barcode is injected as keystrokes (a "wedge"), it will
 * appear here.
 *
 * Test order:
 *   1. Press normal keys ('1' = 49, '2' = 50, ...) to confirm the read works.
 *   2. Press the scan key and scan a barcode - watch for the digits.
 * Esc (27) quits.
