- Update history: examples to show unquoted ISO dates, matching the
corpus convention (every date: in content/ is unquoted) and drop
the misleading 'prevent YAML date parsing' comment — the Haskell
YAML parser keeps the value as a String either way.
- Add a 'Tag-meta sidecars' subsection under Tags explaining that
content/tag-meta/{portal}.md uses a tooltip-only schema with no
title: and no body. Documents the one place in content/ where the
'every file has a title' rule does not apply.
