/*
 * Rahkar theme — desktop header catbar (Digikala-style two-row header).
 *
 * NOT part of the verbatim WP port. This file ADDS to header.css (which stays
 * untouched) the new desktop layout the user asked for:
 *
 *   Row 1 (.rh-row--main)      logo · wide search · account/cart
 *   Row 2 (.rh-row--menu_row)  [ دسته‌بندی کالاها ▾ ]  quick-links…
 *
 * The category trigger opens a pure-CSS mega panel: a vertical list of the
 * top categories on the start side (right, in RTL) and, on hover/focus of a
 * row, a flyout filling the rest of the panel with that category's children.
 *
 * Design notes (speed is the priority):
 *   - ZERO JS. Open/close is :hover + :focus-within only; GPU-composited
 *     (opacity/visibility), no reflow. The panel is in the cache-clean shell,
 *     identical for every anonymous visitor (data = $rahkar_chrome.menu, the
 *     same per-lang cached tree the mobile drawer already uses).
 *   - Desktop only. The .rh-row--menu_row visibility (desktop block / mobile
 *     none) + on-scroll collapse are ALREADY defined in header.css; this file
 *     only styles the bar's contents. Mobile header is unchanged.
 *   - Colors/spacing come from the same theme tokens header.css exposes
 *     (--rh-*  →  --wp--preset--color--*), so it matches the theme palette.
 *
 * Loaded globally right after header.css (theme.yml: priority 33).

 *  Row 1 — make the search the wide center element (logo right, icons left)
 *
 *  :not(.rh-row--split) — this row layout is for the mega-menu/catbar header
 *  mode ONLY, where the centre zone holds a wide search input that should
 *  stretch. RAHKAR_HEADER_MODE='split' also renders its row with the
 *  `.rh-row--main` class (header.tpl), but its centre zone holds the LOGO,
 *  which needs the base `.rh-zone{flex:1 1 0}` equal-thirds from header.css
 *  (so it sits at the row's true centre regardless of how wide the start/end
 *  zones' content is) rather than "shrink to content, centre keeps leftover
 *  space" — without this exclusion the unequal start/end content widths
 *  (nav links vs. icon cluster) pushed the leftover centre space off-centre,
 *  so the logo no longer lined up with anything centred below it on the page.
