+//! p9-fb-24: page-step constant shared by Ask + Inspect PgUp/PgDn.
+//!
+//! Fixed `10` rows per page (independent of viewport height). The
+//! design doc considered viewport-aware paging but deliberately
+//! deferred it — Inspect already shipped with `+/-10`, so unifying
+//! on the same constant is the smallest path that closes the
+//! "Ask has no PgUp/PgDn" feedback. A future viewport-aware upgrade
+//! lives behind this single edit point.
+
+/// Rows scrolled per `PgUp` / `PgDn` keystroke.
