/**
 * Floating Change-Size Button — split out of frontend.css so it can be
 * conditionally NOT enqueued on pages where the Brandoz Filter & Sort Bar
 * widget/shortcode is present (see Brandoz_Frontend::enqueue_assets() and
 * Brandoz_Filter_Sort_Bar_Presence). frontend.css (popup, shortcode picker,
 * inline picker, product-page size pills) still always loads on its own —
 * only this self-contained floating-button block moved here.
 *
 * Position is controlled by the data-position attribute set from PHP/admin.
 * Default fallback = bottom-right.
