/* Eloquentix 25th Anniversary Concert — Ateneul Român.
   Two identities, deliberately held together:
   the poster's world (warm near-black, engraved cream Didone caps, brass) and
   the Eloquentix brand (Source Code Pro, near-zero decoration). The Didone
   names the music; the monospace carries every number — seat, row, price,
   count — where tabular figures and alignment do real work. */
