Two spec gaps the Requirements Engineer flagged on PR #851 are now pinned
as requirements in the #850 issue body and traced here (Status Planned,
flipped to Done as the tasks land):
- REQ-014: a HISTORICAL curated event keeps its full-width WorldBand and
never clusters into a card, even with linked letters.
- REQ-015: a cross-year card sits at its earliest linked letter's
chronological position, never appended after later-dated loose letters.
