Read-only surface
The interface can be explored without creating a claim about an imported historical identity.
LIVE INTERFACE PREVIEW
See the board surface without a fake corpus.
The public demo is an interface preview using synthetic fixture records. It proves the board layout without pretending imported MercuryServer people or posts are live Horizon accounts.
Forum-first layout
The board keeps topics, replies, people, and activity legible in one room.
A hard boundary
A preview does not write into MercuryServer or change the legacy forum.
The corpus-backed Horizon beta remains private and read-only while its migration and privacy gates are held.
