/**
 * Playwright config for the desktop Electron E2E suite.
 *
 * Each test launches a real Electron window backed by the deterministic fake
 * backend (MAKA_E2E=1) against its OWN throwaway userData dir (the fixture
 * mkdtemps one per test), so windows share no *state*. A Runtime Host-backed
 * window owns both Electron and an execution candidate process. Keep the
 * default at one worker: concurrent hidden windows throttle animation frames
 * and share OS focus, invalidating geometry and focus contracts. Developers
 * can still pass `--workers` explicitly for a subset that has neither concern.
 * Deliberately no test count here — the previous note carried a stale one that
 * outlived two rounds of pruning. `playwright test --list` is the only figure
 * that cannot rot.
 *
 * CI shards run on isolated X displays, so jobs still overlap without sharing
 * focus or a compositor. Local parallelism is opt-in for the same reason.
 *
 * Run from apps/desktop via `npm run e2e`, which builds the app first.
