 * Systema Tip Checkout Manager — Cart/Checkout tip inner block.

 * Deliberately inherits the active theme + checkout styling: no hardcoded
 * font-family / font-size and no fixed palette. Colours come from theme.json
 * presets (var(--wp--preset--color--*)) with currentColor fallbacks, spacing
 * uses em so it tracks the surrounding totals text, and the controls reuse the
 * WooCommerce totals rhythm. Tuned to read as part of the Cart/Checkout totals
 * in the active theme (Twenty Twenty-Five / TT5).
