# Darkmoon branding on the CURRENT upstream opencode layout (see Dark-Moon-Front-API
# for full rationale): upstream moved the TUI to @opencode-ai/tui and rewrote
# installation/index.ts + cli/ui.ts (Effect). The old full-file overrides are stale
# and break the build. Minimal, resilient footprint instead:
#   1) Logo    -> pure-data module rendered by packages/tui/src/component/logo.tsx.
#   2) Version -> OPENCODE_VERSION env (script resolver is env-first -> InstallationVersion).
