/**
 * Span builder for symbol mocks.
 *
 * Symbols carry a four-integer span rather than a bare line (#1318), and almost
 * every test that builds one cares about the line alone -- it is asserting which
 * declaration a diagnostic names, not how wide it is. Spelling the other three
 * fields at each site would bury that intent in noise, and a `as never` cast to
 * dodge them is what let mocks drift from the interface before. `ITypeAccessors`
 * had a sibling builder for exactly that reason; #1445 removed the last mock it
 * served, because the module that took those accessors takes a classified plan
 * now and has no accessor literal left to get wrong.
 *
 * Defaults to a zero-width span at the start of the line. A test that asserts a
 * column or a range passes them explicitly.
