Original and edited article wording

Compare every wording change across the three articles. Corrections fix definite errors. House style, clarity, and citation-label edits are optional editorial choices and can be switched off. The full-text view includes unchanged passages.

Scope: the visible article content on PDF pages 1–4, including titles, summaries, contents, body copy, related links, FAQ questions, citations, and tags. Shared website navigation, recommended-post cards, signup forms, and footer text on pages 5–7 are excluded. Twenty FAQ answers were collapsed in the supplied PDFs and were not reconstructed. Line wrapping and PDF font ligatures were normalized in both columns; those are not counted as edits. Original publication metadata is retained. Citation numbers and destinations are retained so the missing FAQ answers can be checked before any source is removed or renumbered. This is an editorial comparison, not a complete legal or service-claim validation.
