/**
 * Optional polyfills — for consumers extending BELOW the library's
 * stated baseline (Chromium 125+, Safari 17.4+, Firefox 129+).
 *
 * **Side-effect-only module.** Importing this file runs feature checks
 * at module-evaluation time and dynamically loads polyfills only when
 * the runtime lacks support:
 *
 * - Popover API (consumers extending to Firefox < 125 / Safari < 17)
 * - CSS Anchor Positioning (consumers extending to Safari < 26 /
 *   Firefox < 147)
 *
 * Browsers with native support skip the download. The polyfill
 * packages (`@oddbird/popover-polyfill`, `@oddbird/css-anchor-positioning`)
 * are optional — if not installed, the import silently fails.
 *
 * Consumers on the stated baseline should NOT import this module — the
 * runtime checks resolve to no-op, but skipping the file avoids the
 * conditional `import()` setup entirely.
 *
 * Runtime mirror: `core/polyfills.js`. `.d.ts` authored in v0.5.6 §191
 * to close the §178 audit-script baseline missing-sibling gap.
 *
 * @see ./polyfills.js (runtime SoT)
