Cosmetic-only — collapses one over-cautious multi-line `throw new Error(...)` into a single line that fits within the project's 100-char `printWidth`. The reformat was produced by lint-staged DURING the amend that landed #70, but applied to the working tree only — the modification never made it back into the staged content of the amend, so the merged commit has the un-prettified version. Spotted because `pnpm exec prettier --check` fails locally; left unchecked, this would break the next PR's `check` job at `format:check`. No behavioural change.
