The phone learns to read whole blocks — CardBodyView renders BodyMarkup's full tree, and the title falls in line

The read view's inline-only AttributedString shim gives way to a real
block renderer over BodyMarkup — the same parse the Mac Preview trusts,
whose swift-markdown dependency project.yml said was already riding
along for exactly this surface. Headings, nested lists with static task
checkboxes, quotes, GFM tables with per-column alignment and clamped
colspans, sideways-scrolling code blocks, literal HTML, dividers, and
tappable absolute links (relative ones stay prose — no folder to
resolve against). The title block sheds its inner padding so its
leading edge sits flush with the body; the tint now grows outward via
a negative background inset instead of pushing the text in. One rich
fixture card body enriched to exercise every block kind; Mac fixture
round-trip suites verified green against it.
