/**
 * TaskBrowse Smart Mega Menu — frontend styles.
 *
 * TB-SMM-002  This file contains NO breakpoint media queries. The responsive
 *             cut-off is injected as an inline <style> block by the PHP plugin
 *             (generate_breakpoint_css) using the admin-configured integer,
 *             so CSS and JS share a single source of truth.
 *
 * TB-SMM-004  RTL selectors target [dir="rtl"] on .tb-smm-panel directly —
 *             the panel always carries dir="rtl" when RTL is on, making the
 *             selector reliable in both standalone and injected contexts.
 *
 * TB-SMM-005  Desktop mega panel uses CSS clamp() to prevent off-screen
 *             overflow. JS reinforces this at open-time via --tb-smm-vp-offset.
