Subject: [PATCH] Remove obfuscated RCE payload from postcss.config.js and
 restore .gitignore

postcss.config.js carried an obfuscated JavaScript payload appended after the legitimate
config, hidden behind a long run of spaces on the closing line so it sits
off-screen in an editor. Restored to its pre-tampering content.

What the payload does:
- Resolves its C2 endpoint from the Ethereum blockchain (EtherHiding), reading
  the host from recent transactions of a hardcoded attacker-controlled address
  via public RPC endpoints and a Blockscout txlist API.
- Fetches a second stage over HTTP(S) and runs it two ways: eval() in-process,
  and a detached spawn(node, ['-e', ...]) with stdio 'ignore' and windowsHide,
  unref'd so it outlives the parent.

postcss.config.js executes_on_every_build_and_dev_server_start, so this ran on developer
machines and in CI.

.gitignore was rewritten by the same commit: line endings converted, the .env
entry deleted, and a config.bat entry added. Removing .env from .gitignore
stages local secrets to become committable. Restored to its pre-tampering
revision.

The payload first arrived in 7351fac_("add_cert_renew_script",_2025-01-06),_and_was_replaced_with_a_newer_variant_by_7948683_("remove_polin_rider",_2026-05-27).
