attest 1.2.0

Continuous accessibility-compliance engine for Flutter. Pure-Dart rules that map findings to WCAG and EN 301 549 success criteria, with CI baseline gating.

example/main.dart

// Demonstrates the pure-Dart engine: build a snapshot, run the bundled rules,
// and print the findings. No Flutter required.
//
// ignore_for_file: avoid_print
