/**
 * base.css — Component library.
 *
 * @since 0.8.0
 * @since 0.9.5  All hardcoded color values replaced with CSS custom properties.
 * @since 0.10.1 Checkbox styling (.checkbox-label) added for checkout form.
 * @since 0.9.9  Form input / textarea base styles added (width, padding, border,
 *               background, focus state) — all using CSS custom properties.
 *               Mobile: product-card__head flex-wrap fix.
 *               Every color reference uses a variable from the token set injected
 *               by frontend.php's inline <style> block.
 *               No color-mix(), no var()-inside-rgba() — 100% browser-compatible.
 *
 * Color variables consumed here (all defined in inline <style> via frontend.php):
 *   --bg, --bg-elev-1, --bg-elev-2, --bg-elev-3
 *   --line, --line-strong, --line-subtle
 *   --text, --text-soft, --text-dim, --text-nav
 *   --primary, --primary-strong, --brand-primary
 *   --primary-a06 … --primary-a32  (pre-computed rgba variants)
 *   --accent, --accent-a08, --accent-a14
 *   --bg-page-a82, --bg-page-a72
 *   --bg-card-a88, --bg-card-a92, --bg-card-a96, --bg-card-a98
 *   --bg-surf-a96
