/**
 * Courses catalog styles.
 *
 * Mirrors the programs catalog: a full-width search bar above a two-column
 * layout — filter sidebar (organization checkboxes with counts, collapsible,
 * with an in-group search box and a fixed-height scrolling option list) beside
 * the results (chips, count + sort, card grid). Structural class names are the
 * plugin's stable contract shared with courses-catalog.php and courses.js.
 *
 * Targets Arabic (RTL) pages but uses logical/flex rules. IBM Plex Sans Arabic
 * is enqueued globally as 'tutor-sso-programs-font' (see tutor-sso.php).
