pub fn check_consistent_help(html: &str, issues: &mut Vec<AccessibilityIssue>)Expand description
WCAG 2.2 — 3.2.6 Consistent Help (Level A).
Build-time verification is partial — full conformance requires
cross-page comparison of help-mechanism placement. This check
emits an info note when a page contains no detectable help link
(anchor text matching help, contact, support, faq).
Cross-page placement consistency is left to a runtime audit and
human review — that’s why crate::CriterionStatus::Manual is used
for this criterion in the compliance matrix rather than wiring this
helper into crate::check_page directly (it would be too noisy on
every clean page that simply omits a help link). Callers that want
cross-page analysis can run this themselves across every page’s HTML
and look for at least one match site-wide.
