/**
 * Sort + filter controls, shared by the make-order list and Quick Shopping.
 *
 * Web mirror of Android's CatalogSortFilterSheets. Both catalogues offer the
 * same axes, so they get the same controls rather than two implementations that
 * drift — which is how the two pages ended up with different sorts.
 *
 * Theme-aware throughout: every colour is a token from colors.css so the
 * controls follow the page in light and dark.
