// MIRROR (data only) of
// packages/editor-ext/src/lib/footnote/footnote-corpus.ts — keep the two in
// sync. Shared golden corpus for the footnote canonicalizer (issue #228): each
// case is { name, input, expected } where `expected` is exactly what
// `canonicalizeFootnotes(input)` must return. Running BOTH the editor-ext copy
// and this MCP mirror against the same corpus makes "the two pure copies behave
// identically" a checkable property without coupling the packages.
