/**
 * `useDrawerSnapPoints` — resolves the configured snap points against the
 * measured popup / viewport geometry, derives offsets, and picks the
 * currently-active snap point.
 *
 * 1:1 port of Base UI React's
 * `packages/react/src/drawer/root/useDrawerSnapPoints.ts`. Solid deviations:
 *
 * - React's `useStableCallback` inside `measureViewportHeight` becomes a
 *   plain function — Solid has no render cycle, callbacks close over the
 *   current signals directly.
 * - `useIsoLayoutEffect` uses the split compute/apply form.
 * - Under happy-dom (test env), `offsetHeight` / `ResizeObserver` return 0
 *   / are absent, so `resolvedSnapPoints` is always `[]` and
 *   `activeSnapPointOffset` is `null`. The test suite exercises the
 *   structural contract; a real-browser pass is required for geometry
 *   correctness.
