heading_check 1.0.0-beta1

First beta release of Heading Check.

Heading Check lets editors inspect the heading structure of a rendered page directly from the Toolbar or Navigation. It runs in the browser, does not change content and does not prevent saving.

Features

• Reports skipped heading levels, empty headings and invalid aria-level values.
• Optional H1 rule: missing, repeated or not the first heading.
• Live status with notice count in the Toolbar (Drupal 11) or Navigation (Drupal 11.3+).
• Outline dialog with filter, jump to heading and highlighting.
• Checks unsaved changes through Drupal's node preview.
• Configurable content region and exclusions.
• Supports closed <details> and ARIA accordions; JavaScript API and adapters for theme accordions.
• German translation included.

Requires Drupal 11. This is a focused editorial tool, not a complete accessibility audit.
