/**
 * Resolves a `snapPoints` array (a mix of pixel numbers and percentage strings e.g.
 * `[200, '50%', '90%']`) into an ascending, de-duplicated array of pixel heights.
 *
 * Each entry is converted with the same {@link convertHeight} rules used by the `height`
 * prop, so percentages are relative to `containerHeight`, values are clamped to it, and
 * the drag handle's height is deducted from the top-most point when applicable. Invalid
 * entries are skipped (never thrown) so a single bad value can't crash a render.
 *
 * The returned array is sorted ascending, therefore a snap `index` refers to ascending
 * order (`0` = smallest/collapsed, `length - 1` = largest/expanded).
 *
 * @param {(number | string)[]} snapPoints raw snap points (px numbers and/or `'x%'` strings)
 * @param {number} containerHeight height the points are resolved/clamped relative to
 * @param {boolean} handleBarHidden whether the drag handle is hidden (affects top clamping)
 * @returns {number[]} ascending, de-duplicated pixel heights (empty if none are valid)
