[1.3.51] - 2026-10-14

Added

• A link to a bzo server shows its icon, name and description in Teams,
  Slack, Discord and the like: the page carries Open Graph tags, written for
  the host it was asked for.
• Search engines and AIs can find and describe every bzo server: its pages
  carry schema.org data -- the game, and on /list every public server --
  /help is the controls and every flag as a page, and each server answers
  /robots.txt, /sitemap.xml, /llms.txt and /llms-full.txt. The entry
  dialog says in a line what the game is, with links to help, the servers
  and the source.
• /apple-touch-icon.png and /apple-touch-icon-precomposed.png answer at
  the site root, where Safari and link-preview crawlers look without reading
  the page.

Fixed

• adminWhitelist matches a link-local IPv6 peer: its address arrives with
  the interface it came in on (fe80::1%ens18), which made it match
  nothing, fe80::/10 included.
• Ace fires two landing shots at a foe holding Shield, which takes one hit
  for its holder; he fired one, and the foe landed with only its flag gone.
