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.
