/* ============================================================================
   The Corpus - browsable evidence grid for cor.demismatch.com
   ----------------------------------------------------------------------------
   Ported from the standalone corpus-grid mock, re-scoped under `.corpus-app`
   so it composes with the shared site chrome (tokens.css + portal.css) instead
   of owning the whole document. Tokens come from tokens.css; the two names the
   mock used that the site spells differently are aliased below. The mock's
   generic `.card` / `.mast` are renamed `.cx-card` / `.cx-hero` to sidestep
   portal.css's own `.card` / `.mast*` rules. All identity (parchment ground,
   oxblood serif, teal/gold offset double-shadow) is inherited verbatim.
