Bulletins

Sysop-curated short notices that appear on the home page and (on
terminals) as the "B" main-menu option.

Adding

/admin/bulletins/ → Add. Fields:

• Title (up to 200 chars)
• Content (markdown supported)
• Pinned (checkbox) — pinned bulletins always sort first
• Expires At (YYYY-MM-DD HH:MM, optional) — after this time the
  bulletin stops showing to users automatically; leave blank for no
  expiry

There's no manual sort-order field and no separate "active/hidden"
toggle — a bulletin is either pinned (shown first) or not, and either
current or expired. To hide one immediately without waiting for its
expiry, delete it or edit Expires At to a time in the past.

Sort order

Bulletins list pinned-first, then newest-first: is_pinned desc, created_at desc.

Cleaning up

Expired bulletins stay in the database (for history/audit) until a
sysop clears them. /admin/bulletins/purge-expired permanently
deletes every bulletin whose expires_at has passed.

Pager view

On terminal, opening a long bulletin paginates with a [Q]=quit
prompt.
