"""Headless test for CONTROLS.html's bindings-loader.
Builds a copy of the page with a self-test harness injected inside its IIFE,
feeds it the fixture (a REAL board-2 migrated bindings.txt: the full defaults
plus two player-authored rows and a wizard section), and writes the result to
%TEMP%\controls_test.html. Run it under headless Chrome and read the
PASS/FAIL lines out of the dumped DOM's :
python scratchpad/test_controls_page.py
chrome --headless=new --disable-gpu --dump-dom file:///%TEMP%/controls_test.html
Asserts: player-authored rows are carried and marked custom, stock rows stay
unmarked, the PgUp/PgDn and backtick built-ins survive unbound keys, wizard
rows land in the extras list, and reset restores the stock board exactly.
Verified 11/11 on 2026-07-26.
