Update feeds

Every change to every standard this calculator carries is published as RSS: threshold changes, scope and legal-status changes, additions and removals. Entries are generated by measuring what each engine actually produces, so a feed item means the guidance moved — not that a file was edited.

Changes that permit more heat exposure than before are labelled explicitly, in the item title and again in its body. Feeds are pull-based: subscribing needs no account or email address, and the site keeps no subscriber list.
