/*
 * santrade-header-v2.css
 * v6 — desktop mega menu title balance: smaller heading scale and tighter icon/title gap so the third column fits into 2 lines.
 * v5 — mobile icon file /img/header/mobile-phone.svg, stable mobile header grid, restored desktop contact link style from v3.
 * v4 — mobile polishing: no mobile "Весь каталог", non-sticky drawer contact card.
 * v3 — Header v2 polish: 1100px breakpoint, compact desktop nav/account, mobile drawer first catalog group logic.
 * v2 — Header v2 base layout, desktop mega menu, mobile sticky drawer, contacts sheet.
 * Scope: only .st-header / .st-mega / .st-mobile-* / .st-contacts.
