// GetHTMLReport produces a self-contained HTML page that:
//
// - Banners the overall DNSViz status of the queried domain.
// - Lists "Fix these first": the curated common-failure matches and any
// critical state, with the human-readable hint pulled from CheckState.Meta.
// - Renders one block per zone in the chain (root → … → leaf), with the
// zone's status, errors and warnings, so a recursive DNSSEC failure
// can be located at the exact level it broke.
// - Falls back to a raw-JSON dump when no rule states were threaded in.
