Blueprint: end_date format changed from 'Y-m-d H:i' to 'Y-m-d' — the
demo frontmatter stores dates without a time component so Admin was
failing to parse it and showing the field empty.
Template: three-case smart range formatting:
- Same month & year → 01 – 03 Sep 2025
- Same year only → 01 Jan – 03 Sep 2025
- Different years → 01 Jan 2025 – 03 Feb 2026

Blueprint: renamed 'Date' to 'Start Date', added optional 'End Date'
field (header.end_date) so it's editable in Admin.
Template: single date → 'd M Y'; range → 'd M Y – d M Y' (full year
on both sides — the old format silently dropped the start year).
