Random Line Picker

In short Picking random lines selects one or more entries from a list at random, using crypto.getRandomValues rather than Math.random. That matters when the draw decides something. Math.random is a pseudo-random generator seeded from the system state, and its output is not designed to resist prediction; the cryptographic source is. For a giveaway with a real prize, or any draw where someone might reasonably ask whether it was fair, the difference is worth having. The selection is without replacement when you pick several, so the same line cannot win twice — which is almost always what a draw means, and is worth confirming because some tools do it the other way. Two practical points for running a draw. Deduplicate the list first, because a name entered twice has twice the chance and that is exactly the objection someone will raise afterwards. And remove blank lines, which are entries as far as the picker is concerned. The remove-duplicate-lines and remove-empty-lines tools do both in a few seconds.
