/**
 * Snapshot Capture — Serializes the live DOM with PII redaction.
 *
 * Used by the visual editor to let an authenticated admin capture an auth page
 * so a translator (without credentials) can later translate it against a
 * frozen copy. The serialized HTML is uploaded to the server and retrieved in
 * viewer mode (?__lr_snapshot={uuid}) where Inspector + Sidebar boot against
 * the snapshot root instead of document.body.
 *
 * Redaction strategy:
 *   - Remove: <script>, <noscript>, <iframe>, <embed>, <object>, editor host
 *   - Clear all form <input>, <textarea>, <select> values
 *   - Replace [data-pii] / [data-sensitive] text with [REDACTED]
 *   - Strip all inline event handlers (onclick, onmouseover, etc.)
 *   - Inline PII redaction in text nodes (email / phone / URL / SSN /
 *     credit card / IPv4) — see pii-redactor.ts. `[data-no-redact]`
 *     subtrees, `<code>`, and `<pre>` are skipped.
 *   - Strip CSRF/CSP meta tags and auth tokens from link/script URLs

 * Pure function — does NOT mutate the live DOM. Clones first, then:
 *   1. Extracts block keys BEFORE redaction (so auto_keys match the live page)
 *   2. Redacts the clone (strips PII, scripts, forms, etc.)
 *   3. Stamps each block element with a data-lr-snap-idx attribute so the
 *      viewer can map a click back to the pre-computed key
 *   4. Serializes to HTML
 *
 * The textEntries carry pre-computed keys (no source text) and the HTML is
 * safe to store. The viewer uses textEntries to look up the correct key by
 * index when the translator clicks a block.
