/**
 * Re-points --lsg-theme-radius at theme 3's pill when the page is set to Pill.
 *
 * Idempotent and reversible: the previous override is always cleared before the
 * value is read. That matters for Storybook, where one document serves all three
 * themes and both toolbars change live — without the reset, an inline 80px would
 * mask the incoming value and the override could never be re-evaluated. On an AEM
 * page neither the theme nor the shape changes after load, so it runs once.
 *
 * @param active Whether theme 3 is the active theme. Always true in AEM, where
 *   theme-3.js only loads on theme-3 pages; the Storybook toolbar drives it.
