Run `prettier --write src` over ui-tui-opentui-v2 to normalize formatting to the repo .prettierrc (no semicolons, single quotes, width 120, arrowParens avoid, trailingComma none). This worktree had pre-existing prettier-version divergences across 19 files; normalizing is correct. No behavior changes — formatting only. The gate (type-check → lint → bun test) stays green.
