/**
 * SBX disclosure — loads only when a disclosure region (the size guide,
 * §22.2, 0.3.0) is rendered (§11).
 * Pre-enhancement: a <details> under the buttons, its summary the same plain
 * ruler link the enhanced state shows (readable, no JS; §14.1).
 * Post-enhancement (.sbx-disclosure--enhanced): a text link that opens a
 * pop-up appended to <body>: centred on desktop, a bottom sheet on a phone
 * (§15). Since 0.3.3 the size guide's link sits on the Size row, right-aligned
 * (.sbx-disclosure-host). Longhands before `inset`, `-webkit-backdrop-filter` before
 * `backdrop-filter`, no flex `gap`, prefix media queries: the product page's
 * Safari 12 floor (review P21).
