Copies .dockerignore, .gitignore, .prettierignore, check.yml and REPO_POLICIES.md from sneak/prompts at dd4027b, keeping the repo's own entries (dist/, release/, yarn files) after the canonical content. The Dockerfile gets separate lint and test phases; its last stage depends on both, checks the git describe version and runs make build. script/lint, test, check, cibuild and docker are the canonical models. check-censored moves into the lint phase and test-verify-build into the test phase. fmt and fmt-check fall back to the nvm-installed node. The e2e image builds are uncached. Comments citing the old test caps or what runs a script are updated. Model: opus-5-5

// balanceLine() is the row that issue #307 was reported against: every

// string it emits, which is what gets assigned to innerHTML.

// The browser half of the same claim — that a real Chrome renders that
