/**
 * CIT Staff Directory — frontend styles.
 *
 * Design intent: an institutional faculty directory — editorial portrait cards,
 * restrained palette (tinted neutrals + navy primary load-bearing), teal accent
 * used sparingly. Inherits the site-wide --cit-* tokens via .cit-ui.
 *
 * All directional spacing uses logical properties (margin-inline, inset-inline)
 * so the same rules read correctly in RTL (Arabic) and LTR (English) pages.
