/* ===== FOOTER =====
 *
 * The footer is a real 3-column grid: the language switcher occupies the
 * left column, the "Powered by" label stays centred in the middle column,
 * and the footer-links block (订单查询 / affiliates) sits in the right
 * column. Using grid (instead of the old flex-center + absolute hack)
 * means every item is in the document flow and wraps cleanly on narrow
 * viewports; no element has to be pulled out of the layout with
 * position:absolute any more.
 *
 * Background intentionally uses --bg (NOT --titlebar-bg) so the footer
 * bar merges seamlessly with whichever shop-page is showing above it.
 * With the old titlebar-bg tint the footer looked noticeably brighter
 * on the affiliates page (where the surrounding area is a large solid
 * fill) compared to the products page (where the cards broke up the
 * contrast). A thin border-top line is enough to delimit the footer
 * from the content without painting the whole strip a lighter colour.

 * shadow — the switcher reads as an inline footer link pair and
 * automatically picks up both dark and light themes through the same
 * CSS variables (`--muted`, `--accent`) that the rest of the footer
 * uses. Active language takes the accent colour, inactive fades to the
