# verify-web-input.sh - Typed-character acceptance gate for the web port.
# Runs KEYS's page in headless Chromium at one canvas pixel per stage pixel
# (KEYS.html?scale=1&aspect=square), types the RetroNet definition-of-done
# string as browser key events carrying their text (scripts/lib/webDriver.mjs,
# over the DevTools protocol), takes the canvas, and decodes the example's
# verification scanline (row 198) with scripts/lib/keysRow.py, as the SDL3
# and DVX gates do.
#
# Usage:   scripts/verify-web-input.sh
# Requires: Chromium, emsdk's node, python3 + PIL; build/web/bin/KEYS (make web).
