How to verify

Save the article element (<article id="lc-piece">) exactly as served on the piece page.
Hash it with SHA-256 and compare the result with the published HTML hash on this page.
The .ots proof, once submitted, is checked against the OpenTimestamps calendars and then Bitcoin.
A match shows the text existed then. It does not show the text was right.
