/**
 * Lock-shortcut classifier self-test (lock-shortcuts.mjs).
 *
 * Table-driven coverage of the two pure predicates the before-input-event guard
 * in src/main/index.ts is built from. This is the decision v1.0.17 got wrong
 * from inside an untestable closure, so every chord spelling that matters is
 * pinned here:
 *   - the panic lock is exactly Ctrl+L: Shift (IME switch on zh/ja) and Alt
 *     (AltGr on European layouts) must pass through, as must Caps-Lock 'L'
 *     variants only when they really are Ctrl+L
 *   - the locked-window blocklist: reload (F5, Ctrl+R, Ctrl+Shift+R), zoom in
 *     both plain and Shift-shifted spellings ('='/'+' and '-'/'_'), reset ('0'),
 *     and DevTools (Ctrl+Shift+I/J/C)
 *   - what must NOT be blocked: plain typing, Ctrl+C copy, Ctrl+L itself while
 *     already locked (it falls to the page), and unrelated Ctrl chords
 *
 * Build: node tests/build-bundles.cjs
 * Run:   node tests/lock-shortcuts.mjs   (must exit 0)
