$NAME is at $DEST (port $PORT, $DOMAIN).

Next:
  1. Replace src/lib/game/index.ts with your game, keeping the GameSpec shape,
     and src/lib/components/Board.svelte with its board. Keep the tests green.
  2. Fill in the hall's pitch, tag and about panel (src/lib/components/Hall.svelte),
     the rules page, the guide, src/app.html's description, and the palette in src/app.css.
  3. Create the droplet (deploy/README.md), then replace __IP__ everywhere:
       grep -rl __IP__ . --exclude-dir=node_modules | xargs sed -i '' 's/__IP__/<ip>/g'
  4. Create a Sentry project (the Sentry MCP can) and put its DSN and project id
     in deploy/$SLUG.service and deploy/sentry-slack-alert.sh.
  5. deploy/deploy.sh <ip>
docs/conventions.md is the house style every game follows.
