 * Register: investment-committee / management-consulting. Formal first, feminine
 * through restraint (soft rose motifs, warm cream, high-contrast serif display),
 * never decorative-for-its-own-sake. One deep accent (plum), one soft accent
 * (sakura), warm rose-tinted neutrals, refined sage/rose semantics.
