Files vendored from this commit:

  data/default_game.json         — still tracked as-is (initial game state)

  data/ruleset_3.de.json         — split once (by a since-deleted extraction
  data/ruleset_3.en.json           script, see git history) into:
                                   data/ruleset_base.json
                                   i18n/ruleset.en.json
                                   i18n/ruleset.de.json

The original ruleset_3.* files are no longer tracked; the game merges
base + locale at runtime.

The three split files are now hand-maintained: i18n/ruleset.{en,de}.json
carry translations and item descriptions written for this port, so they
can no longer be regenerated from upstream.  To pick up an upstream change:

  git clone https://github.com/datadealer/dd_rules.git
  cd dd_rules
  git diff 9290ab97a9ab7623d85290541cb44173b7a908d9 -- default_game.json ruleset_3.de.json ruleset_3.en.json
  # Port the relevant hunks by hand into data/ruleset_base.json and
  # i18n/ruleset.{en,de}.json (default_game.json can be copied directly).
