function Get-SecretSharingWordlist {
    <#
    .SYNOPSIS
        Returns the official 1024-word SLIP-0039 English wordlist.
    .DESCRIPTION
        Loads (once, cached for the module session) Private/Wordlist/wordlist.txt - the
        wordlist sourced verbatim from the SLIP-0039 reference implementation
        (trezor/python-shamir-mnemonic). A word's position in this list (0-1023) is its
        10-bit mnemonic value; the file's alphabetical ordering is incidental to how the
        words were selected, not something this mapping depends on.
