/* ============================================================
 * Alcedo Trading — alcedotrading.com
 *
 * An engraved plate, not a terminal. The page is a single sheet:
 * a hairline frame, a masthead line, a vignette of the kingfisher
 * cut in guilloché, a title block, and two ruled entries. Rules and
 * whitespace do the structural work — there are no filled cards.
 *
 * The display face (Bodoni Moda) appears exactly twice, always large.
 * Everything under ~28px is Spectral. Mono survives in two places
 * only: the take() motif and the line where the server answers.
