// Local patch: self-host attribution box (applied at image build time).
|
|
//
|
|
// The AdventureLandOnlyUse license requires a crawlable link back to
|
|
// https://adventure.land, and the original project should not appear to
|
|
// support a self-hosted instance. The upstream login/character-selection help
|
|
// box (htmls/contents/account_help.html) shows "Email, for anything:
|
|
// hello@adventure.land" from a phrase. This patch points that component at
|
|
// pages.attribution.self-hosted instead, which ships as
|
|
// docker/attribution/{en.js,de.json}; all other languages fall back to English.
|
|
//
|
|
// The script fails loudly when the upstream phrase is gone or the shipped
|
|
// catalog is incomplete, so a code update cannot silently drop the attribution.
