 1// Package humanizedemo is a small gnoweb demo of the human-facing formatters
 2// provided by the [p/moul/x/daily/humanize](/p/moul/x/daily/humanize/v0)
 3// library: byte sizes, thousands separators, ordinals and block counts.
 4//
 5// It contains no formatting logic of its own. Stateless, so Render is
 6// deterministic.
