  3# Run the accessibility audit suite against real simulator runtimes.
  4#
  5#   ./Scripts/audit-a11y.sh            # floor + current
  6#   ./Scripts/audit-a11y.sh floor      # oldest supported runtime only
  7#   ./Scripts/audit-a11y.sh current    # newest installed runtime only
  8#
  9# Why this exists rather than living entirely in CI: audit coverage is NOT
 10# nested across OS versions — each runtime reports findings the others miss, in
 11# both directions. Measured on Tracked Domains, iOS 18.6 reported 2 findings and
 12# iOS 27.0 reported 6; at accessibility text sizes the Dashboard produced a
 13# hit-region finding on 18.6 that 27.0 did not. The GitHub macos-26 image ships
 14# only iOS 26.x runtimes, so it structurally cannot cover the floor. This machine
 15# can.
 16#
 17# CI covers "current" on a clean checkout (which a local run cannot, since it
 18# would miss an uncommitted file). This script covers "floor" (which CI cannot).
 19# Together they cover both; neither duplicates the other.
 20#
 21# The deployment target is read from the project rather than hard-coded, so it
 22# cannot drift out of sync.
