- JournalPostCard: the title link is the card's only anchor; the image is
no longer a link and the separate read-more link is gone; the whole card
stays clickable through a CSS stretched link with the focus ring on the
card; prop headingLevel (2 | 3, default 2)
- related posts keep their h2 and render their cards at h3; JournalPostList
passes headingLevel through
- smoke checks headings=strict (one h1, no skipped level) and cardlinks=N
on every fixture page; expectation files for postTitleTag forced to h1
and p (the documented two-h1 and no-h1 consequences)
BREAKING CHANGE: .journal-post-card__more and the image link
(.journal-post-card__image is now a div) are removed from post cards.
