// exact same key name for free via the browser's shared per-origin
// storage, rather than an independent copy that could drift.

// the only writer today; `Row.tsx` is the only reader.

// (long tool-results, Write/Edit diffs, …) should default open. Pure
// client-side — no backend field, nothing round-trips through
// `/api/*`. Read live (not cached) by the shared terminal factory's
// `expandDetails` option — see docs/web-ui/shape.md::Shared terminal
// pane — so a preference change applies to the next rendered row in
// any already-open agent tab without a reload.
