# Aggregate E2E pass/fail counts across all per-suite summary lines.
#
# Each test-*-e2e.js emits a summary line in one of these shapes:
#   "N passed, M failed"             — most suites (=== Results: 4 passed, 0 failed ===)
#   "passed N failed M"              — observer-iata style
#   "N/T tests passed[, M failed]"   — issue-1224 / 1236 / 1273 style
#   "N/T PASS"                       — logo-* suites
#   "N/T passed"                     — nav-fluid / nav-priority / nav-more-floor
#   "<file>.js: PASS"                — single-test suites (hamburger-dropdown)
#   "<file>.js: FAIL ..."            — suite-level failure
#
# Per-test progress lines (leading whitespace + PASS:/FAIL:/✓/✗) are skipped to
# avoid double-counting. Each suite's summary is matched by the FIRST pattern
# that fits, so a single line cannot contribute to two counters.
#
# Usage: aggregate-e2e-pass.sh [path-to-e2e-output.txt]
# Prints:  PASS=<n> FAIL=<n>
